Located on the shores of San Pablo Bay, the city had a population of 126,090 at the 2020 census. Vallejo is home to the California Maritime Academy, Touro University California and Six Flags Discovery Kingdom.

Vallejo is named after Mariano Guadalupe Vallejo, the famed Californio general and statesman. The city was founded in 1851 on Gen. Vallejo's Rancho Suscol to serve as the capital city of California, which it was 1852–1853, after which the Californian government moved to neighboring Benicia, named in honor of Gen. Vallejo's wife Benicia Carrillo de Vallejo. The Mare Island Naval Shipyard was founded in 1854, and defined Vallejo's economy until the turn of the 21st century.

Vallejo was once home of the Coast Miwok as well as Suisunes and other Patwin Native American tribes. There are three confirmed Native American sites located in the rock outcrops in the hills above Blue Rock Springs Park. The California Archaeological Inventory has indicated that the three Indian sites are located on Sulphur Springs Mountain.

The city of Vallejo was once part of the 84,000-acre (340 km2) Rancho Suscol Mexican land grant of 1843 by Governor Manuel Micheltorena to Gen. Mariano Guadalupe Vallejo. The city was named after this Mexican military officer and title holder who was appointed in settling and overseeing the North Bay region. Gen. Vallejo was responsible for military peace in the region and founded the pueblo of Sonoma in 1836.

In 1846, independence-minded Anglo immigrants rose up against the Mexican government of California in what would be known as the Bear Flag Revolt which resulted in Gen. Vallejo's imprisonment in Sutter's Fort. This was subsequently followed by the annexation of the California Republic to the United States. Gen. Vallejo, though a Mexican army officer, generally acquiesced in the annexation of California to the United States, recognizing the greater resources of the United States and benefits that would bring to California.

In 1851, Vallejo was declared to become the official California State Capitol, with the new government prepared to meet for the first time the following year. In 1852, the legislature convened for the first time. However, Vallejo did not follow through with constructing a Capitol State Building for them to meet in. In 1853, it was again the meeting place for the legislature, solely for the purpose of moving the capitol officially to Benicia, which occurred on February 4, 1853, after only a month. Benicia is named after Vallejo's wife, Benicia de Vallejo. After the legislature left, the government established a naval shipyard on Mare Island, which helped the city overcome the loss. Due to the presence of the shipyard, Filipinos began to immigrate to Vallejo beginning in the first decades of the 20th century. The yard functioned for over a hundred years, finally closing in 1996.

The U.S. government appointed the influential Vallejo as Indian agent for Northern California. He also served on the state constitutional convention in 1849. Afterward, Vallejo remained active in state politics, but challenges to his land titles around Sonoma eventually left him impoverished and reduced his ranch from 250,000 acres to a mere 300. He eventually retired from public life, questioning the wisdom of his having welcomed the American acquisition of California in the first place. Vallejo died in 1890, a symbol of the eclipse of Californio wealth, power, and prestige.

Although the town is named after Gen. Vallejo, the man regarded as the true founder of Vallejo is John B. Frisbie. After his daughter Epifania married Frisbie, Gen. Vallejo granted him power of attorney for the land grant. It was Frisbie who hired E. H. Rowe, the man who designed the city layout and who named the east–west streets after states and the north–south streets after California counties.

Mare Island Naval Shipyard was a critical submarine facility during WW II, both for constructing and overhauling vessels.

Downtown Vallejo retains many of its historic Victorian and Craftsman homes.

On May 6, 2008, the city council voted 7–0 to file for Chapter 9 bankruptcy, at the time becoming the largest California city to do so. Stephanie Gomes, Vallejo City Councilwoman, largely blames exorbitant salaries and benefits for Vallejo firefighters and police officers. Reportedly, salaries and benefits for public safety workers account for at least 80 percent of Vallejo's general-fund budget. On November 1, 2011, a federal judge released Vallejo from bankruptcy after nearly three years.

According to United States Census Bureau, the city has a total area of 49.5 square miles (128 km2). Land area is 30.7 square miles (80 km2), and 18.9 square miles (49 km2) (38.09%) is water. The Napa River flows until it changes into the Mare Island Strait in Vallejo which then flows into San Pablo Bay, in the northeastern part of San Francisco Bay.

Vallejo is located on the southwestern edge of Solano County, California in the North Bay region of the San Francisco Bay Area in Northern California. Vallejo borders the city of Benicia to the east, American Canyon and the Napa county line to the north, the Carquinez Strait to the south and the San Pablo Bay to the west.

Several faults have been mapped in the vicinity of Vallejo. The San Andreas Fault and Hayward Faults are the most active faults, although the San Andreas is at some distance. Locally, the Sulphur Springs Valley Thrust Fault and Southampton Fault are found. No quaternary seismic activity along these minor faults has been observed with the possible exception of a slight offset revealed by trenching. The Sulphur Mountain and Green Valley faults have been associated with the Concord Fault to the south. The Concord Fault is considered active.

Historically there have been local cinnabar mines in the Vallejo area. The Hastings Mine and St. John's Mine contribute ongoing water contamination for mercury; furthermore, mine shaft development has depleted much of this area's spring water. Both Rindler Creek and Blue Rock Springs Creek have been affected.

Vallejo has a mild, coastal Mediterranean climate and can be an average of 10 Â°F (−12 Â°C) cooler than nearby inland cities. Vallejo is influenced by its position on the northeastern shore of San Pablo Bay, but is less sheltered from heatwaves than areas directly on or nearer the Pacific Ocean/Golden Gate such as San Francisco and Oakland. Although slightly less marine, average temperatures range between 8 Â°C (46 Â°F) in January and 19.8 Â°C (67.6 Â°F) in July. However, summer is very long with June–September being almost equal in historical average temperatures. This seasonal lag sees October averages being higher than in May in spite of it being after the Equinox (meaning less daylight than darkness).

Vallejo was named the most diverse city in the United States in a 2012 study by Brown University based on 2010 census data, and the most diverse city in California by a Niche study based on 2017 American Community Survey data. In 2022, Vallejo was again named the most diverse small town in America, with a 77% chance any two residents would be of a different census racial category. Hispanics comprise 28% of the local population, 23% are White, 23% are Asian, 19% are Black, and 7% are of mixed or other heritages.

According to the city's 2022 Annual Comprehensive Financial Report, the top employers in the city are:

In recent years, Vallejo has attracted a large community of artists to the region in search of lower rent and larger work-spaces. Artists pushed out of larger Bay Area cities like San Francisco and Oakland have been working with city leaders to revitalize the once blighted downtown area.

The artist-run Vallejo Art Walk scheduled on the second Friday of every month in downtown Vallejo has been recognized as a hub for artists in the Bay Area and the entirety of California.

As early as the 1940s and before, Vallejo is known to have had a well-formed gay community, which was a short drive or boat ride away from San Francisco. At one time Vallejo boasted eight gay bars. After a migration of gays and lesbians from San Francisco in the decade 2000–2009, openly gay members of the community encountered what they described as a backlash against them. The school district was threatened by the ACLU with a lawsuit for harassment on behalf of a 17-year-old lesbian by school administrators. The school settled the lawsuit with the student. The school agreed to pay her $25,000, adopt a more stringent non-discrimination policy, and include a curriculum that positively portrayed gay and lesbian people.

The Government of Vallejo is defined under the Charter of the City of Vallejo. It is a council–manager government and consists of the Mayor, City Council, and numerous departments and officers under the supervision of the City Manager, such as the Vallejo Police Department, Vallejo Fire Department, Vallejo Public Works Department, and Vallejo Economic Development Department. As of February 2023, the council consists of Robert McConnell (Mayor), Rozanna Verder-Aliga (Vice Mayor), Diosdado "JR" Matulac, Mina Loera-Diaz, Charles Palmares, Peter Bregenzer, and Cristina Arriola.

Residents of Vallejo participate in elections for Solano County Board of Supervisors Districts 1 and 2. As of November 2022, these seats were represented by Supervisors Erin Hannigan and Monica Brown, respectively.

In the California State Legislature, Vallejo is in the 3rd Senate District, represented by Democrat Christopher Cabaldon, and in the 14th Assembly District, represented by Democrat Buffy Wicks. In the United States House of Representatives, it's in California's 5th congressional district, represented by Republican Tom McClintock.

In 2008 the government of Vallejo filed for bankruptcy. A judge declared the bankruptcy over in 2011, but analysts have noted that the city did little to resolve its largest expense—public pensions—and may face a second round of bankruptcy.

As of September 2022, there were 69,546 registered voters in Vallejo; of these, 40,818 (58.7%) are Democrats, 8,751 (12.6%) are Republicans, and 15,612 (22.4%) stated no party preference.

On April 17, 2012, the City Council approved the first citywide participatory budgeting (PB) process in the United States. The Council allocated $3.4 million to the Vallejo PB process and since then, Vallejo residents and business and property owners have been developing and designing project ideas. They have vetted and reduced more than 800 project ideas to 36 projects that will be on the ballot. Vallejo residents 14 years of age and older will vote and choose six out of 36 projects to vote on from May 11 through May 18, 2013.

The second cycle of participatory budgeting in Vallejo was initiated on February 4, 2014, with $2.4 million allocated. A public vote open to all residents of Vallejo age 16 and over took place in October 2014.

Vallejo has had one of California's highest rates of police killings in recent years. A 2023 Vallejo Sun story described Vallejo's police department as "one of California’s most deadly." In 2020, the department engaged a consulting firm to assess how to address extensive killings by its officers. The firm issued 45 recommendations, which were endorsed by the California attorney general; but according to reporting from the Vallejo Free Press and ProPublica, only two of the recommendations had been fully implemented by 2022.

Vallejo has seen a rate of killings by police officers that is significantly higher than the national average and other Bay Area cities. These incidents included the fatal shooting of Willie McCoy by six officers in 2019 and the shooting of Sean Monterrosa, who was unarmed, during protests following the murder of George Floyd in 2020. One of the officers who killed McCoy had previously killed an unarmed man as he fled, while another killed three men over a five-month period and was later promoted. Vallejo Police killed 19 people between 2010 and 2020. In 2012, police shootings accounted for six of the 20 homicides to occur in the city, and the frequency of officer-involved shootings stood at around 38 times the national rate.
