The community began when W.S. Peters agreed to bring 600 families into the area within a three-year period as part of a land grant. Families began arriving in the summer of 1848. In 1849, Tarrant County was established and named for General Edward H. Tarrant. The community of Birdville (adjacent to what is now the southwest boundary of North Richland Hills) was named the first county seat. The area remained a rural farming and ranching community for more than 100 years.

In 1952, Clarence Jones began to subdivide his 268-acre (1.08 km2) dairy farm into a suburban addition in the area that is now Cummings Drive. In 1953, the North Richland Hills Civic League sought to have the area annexed to Richland Hills, then voted to form their own city when annexation was denied. An election was held, and the 268 acres (1.08 km2) of the Jones Farm, with a population of 500, became officially incorporated as the City of North Richland Hills.

The first section of streets in North Richland Hills was named for the local families. The second section, which was added in 1954, was named for automobiles. There were 188 homes in the first part of the subdivision, which was restricted to brick and masonry construction.

By 1957, the North Richland Hills' boundary was within 2 miles (3 km) of Smithfield, and by 1960, Smithfield had been annexed into North Richland Hills. In 1960, the population of North Richland Hills was beginning to rise at 8,662 residents, with that number more than doubling to 16,514 by 1970. The city's population continued to grow at a rapid pace, with the 1980 census at 30,592, and the 1990 census reflecting 45,895. In 2000, the population was at 55,635, and rise to 63,343 at the 2010 census. In 2020, the population was at 69,917.

According to the United States Census Bureau, the city has a total area of 18.2 square miles (47.2 km2), of which 18.2 square miles (47.1 km2) is land, and 0.04 square miles (0.1 km2), or 0.24%, is water.

North Richland Hills operates under a charter adopted in 1964, which provides for a “Council-Manager” form of government.

The city of North Richland Hills is a voluntary member of the North Central Texas Council of Governments association, the purpose of which is to coordinate individual and collective local governments, and facilitate regional solutions, eliminate unnecessary duplication, and enable joint decisions.

The North Richland Hills Fire Department (NRHFD), also called the North Richland Hills Fire-Rescue (NRHFR), is a public health service geared towards combating uncontrolled fires. In addition to its role as a fire department, it acts like a traditional EMS service, and is dispatched to a wide range of medical emergencies unrelated to fires. To accomplish this mix of roles, all NRHFD staff are cross trained as firefighters and paramedics; likewise, all vehicles that they employ carry advanced life support equipment.
