Malden is a city in Middlesex County, Massachusetts, United States. At the time of the 2020 U.S. Census, the population was 66,263 people.

Malden is a hilly woodland area north of the Mystic River that was settled by Puritans in 1640 on land purchased in 1629 from the Mystic tribe of the Pawtucket Confederation, with a further grant in 1639 by the Squaw Sachem of Mistick and her husband Webcowet. The area was originally called the "Mistick Side" and was a part of Charlestown. It was incorporated as a separate town in 1649 under the name "Mauldon". The name Malden was selected by Joseph Hills, an early settler and landholder, and was named after Maldon, England. The city originally included the adjacent cities of Melrose (until 1850) and Everett (until 1870).

At the time of the American Revolution, the population was about 1,000 people, and the citizens were involved early in resisting British rule. They boycotted the consumption of tea in 1770 to protest the Revenue Act of 1766, and it was also the first town to petition the colonial government to secede from the British Empire.

Like many communities in New England, many towns and neighborhoods are organized around squares, which are located at the crossroads and town commons dating back from the colonial times and the early 19th century. Many of the neighborhoods take their name and identity from the main square in their area.

Malden's squares include Malden Square (at Main and Pleasant streets), Converse Square (at Main, Salem, and Ferry streets) Oak Grove Square (at Oak Grove T Station), Bellrock Square (at the intersections of Cross, Main and Medford streets), Judson Square (near Ferryway School), former Suffolk Square (at Cross and Bryant streets), once the location of a thriving Jewish community, Maplewood Square (at Lebanon, Maplewood and Salem streets) and Linden Square.

Some of the neighborhoods in Malden include Faulkner (location of the former Suffolk Square), West End, Edgeworth, Linden, Ferryway, Forestdale, Maplewood, Bellrock, and Belmont Hill (located between Bellrock and Ferryway).

Bellrock is the south central section of the city, bordered by Main Street on the east, Charles Street on the north, the Malden River on the west, and the Everett line on the south. It contains Bell Rock Memorial Park (listed on the National Register of Historic Places) and Bell Rock Cemetery (also listed), which contains marked graves dating back to 1670. Bell Rock Cemetery was called Sandy Bank until the establishment of the Salem Street Cemetery in 1832; it was then known as the Old Burial Ground for half a century until it was renamed in 1882. Also located in this area are the headquarters for New England Coffee.

The Edgeworth neighborhood is the southwestern section of the city. It contains Devir Park, Pearl St. Park, and Callahan Park. The city's football stadium, Macdonald Stadium is in Edgeworth. A school in Edgeworth is the former Emerson grammar school. The Converse Rubber Factory and offices once operated in Edgeworth at the bottom of Pearl Street.

In 1847, Joshua Webster, president of the Saugus Branch Railroad, purchased 200 acres in Malden along its projected route. Here, he planned a residential development with wide streets and ornamental trees. Due to the hundreds of maple trees Webster planted, the neighborhood became known as Maplewood.

The city government of Malden includes a mayor and city council. The mayor is elected to a four-year term. As of May 2021, the mayor is Gary Christenson. Christensen was most recently elected to this position on November 5, 2019 and his current four-year term expires at the end of 2023.

The Malden City Council has eleven elected members. Eight of these members are elected from the city's eight wards and are known as Ward Councillors. Three of the members, known as Councillors-at-Large, are elected city-wide. All eleven are elected to two-year terms.

One limited access route, U.S. 1, runs through the city, connecting Boston to the North Shore suburbs. Additionally, Route 28, Route 60 and Route 99 run through Malden as arterial routes. Route 16 and Interstate 93 are a short distance outside the city's borders.

The city is served by the Orange Line subway that connects it to downtown Boston. The city's subway stops are Malden Center and Oak Grove. The MBTA's commuter rail also has one stop in the city (Malden Center) and can stop at Oak Grove if necessary. During the first few years of the 2000s, the MBTA updated signal systems and Orange Line service was replaced by shuttle buses at night. Since September 2007, such service interruptions have been limited to occasional weekends, while signal system repairs necessitated closing off the northern portion of the Orange Line and rerouting passengers via replacement bus service from either the Haymarket subway stop or Wellington Station.

There is a sizable section of the old Boston and Maine Saugus Branch Railroad line running across the middle of Malden. This line is currently owned by the MBTA, but has been out of use since 1993 and has not seen passenger service since 1958. The Saugus Branch Railroad has now been converted into a 10-foot wide multi-use trail known as the Northern Strand Trail (aka Bike to the Sea Trail) which opened in December 2012. The paved section of Northern Strand trail currently extends from Wellington Street in Everett through Linden Square at the Malden/Revere. The unpaved section of the trail as of July 2019 runs through Revere and Saugus to Boston Street at the Lynn line. Trail extensions to the Mystic River / Encore Casino in Everett and paving the trail thru Revere, Saugus and to Western Avenue in Lynn will be built starting in Fall 2019. The City of Lynn and the Department of Conservation and Recreation will also be building a separated bicycle lane through Lynn Common, down Market Street and the Lynnway to Lynn and Nahant Beaches. The Malden section of the trail features the "ArtLine" a series of murals and sculptures created through the efforts of Malden Arts. Malden ArtLine

Bus service to all adjacent communities is also available via the service of the MBTA.
