Tucumcari (/ˈtuːkəmˌkæriː/; TOO-cum-carry) is a city in and the county seat of Quay County, New Mexico, United States. The population was 5,278 at the 2020 census. Tucumcari was founded in 1901, two years before Quay County was established.

In 1901, the Chicago, Rock Island and Pacific Railroad built a construction camp in the western portion of modern-day Quay County. Originally called Ragtown, the camp became known as "Six Shooter Siding", due to numerous gunfights. Its first formal name, Douglas, was used only for a short time. After it grew into a permanent settlement, it was renamed Tucumcari in 1908. The name was taken from Tucumcari Mountain, which is situated near the community. The origin of the mountain's name is uncertain; it may have been derived from the Comanche word tʉkamʉkarʉ, which means 'ambush'. A 1777 burial record mentions a Comanche woman and her child captured in a battle at Cuchuncari, which is believed to be an early version of the name Tucumcari.

In December 1951, a water storage tank collapsed in the city. Four were killed and numerous buildings were destroyed.

In 2014, a series of suspicious fires destroyed abandoned buildings, including the Tucumcari Motel, Payless Motel, and a house in the 500 block of North Fourth Street. A former Tucumcari Police Department officer and several others have been charged with arson.

The town formerly hosted an air show each year. The show held on October 4, 2006, was canceled after one hour when a single-engine plane crashed, resulting in the pilot's death.

Tucumcari until the mid-twentieth century was a junction for transcontinental train service. The Rock Island Railroad ran pool train operations with the Southern Pacific (originally the El Paso and Northeastern Railway), with transfers at the station (for the Tucumcari-Los Angeles leg of the trip). The Choctaw Rocket (Memphis-Little Rock-Tucumcari-El Paso-Los Angeles) made the switch there (for the coach cars). The Golden State (Chicago-Kansas City-Topeka-Tucumcari-El Paso-Los Angeles) ran continuously through the town.

The buildings formerly at Metropolitan Park (locally known as "Five Mile Park" because it is located about five miles (8 km) outside of town) were designed by Trent Thomas, adapted from his design of La Fonda Hotel in Santa Fe. The park once featured New Mexico's largest outdoor swimming pool. Owing to deterioration, Metropolitan Park was named to the New Mexico Heritage Preservation Alliance's list of Most Endangered for 2003. In 2010, the park's main building caught fire and burnt to the ground. The city of Tucumcari razed the site weeks after the fire.

For many years, Tucumcari has been a popular stop for cross-country travelers on Interstate 40 (formerly U.S. Route 66 in the area). It is the largest city on the highway between Amarillo, Texas and Albuquerque, New Mexico. Billboards reading "TUCUMCARI TONITE!" placed along I-40 for many miles to the east and west of the town invite motorists to stay the night in one of Tucumcari's "2000" (later changed to "1200") motel rooms. The "TUCUMCARI TONITE!" campaign was abandoned in favor of a campaign which declared Tucumcari, "Gateway to the West". However, on June 24, 2008, Tucumcari's Lodgers Tax Advisory Board, the group responsible for the billboards, voted to return to the previous slogan.

Old U.S. Route 66 runs through the heart of Tucumcari via Route 66 Boulevard, which was previously known as Tucumcari Boulevard from 1970 to 2003 and as Gaynell Avenue before that time. Numerous businesses, including gasoline service stations, restaurants, and motels, were constructed to accommodate tourists as they traveled through on the Mother Road. A large number of the vintage motels and restaurants built in the 1930s, 1940s, and 1950s are still in business despite intense competition from newer chain motels and restaurants in the vicinity of Interstate 40, which passes through the city's outskirts on the south.

Tucumcari is the home of over 50 murals. Most were painted by artists Doug and Sharon Quarles and serve as a tourist attraction.

Most of Tucumcari's oldest buildings lie along or near Main Street in the Historic Downtown area. These include:

• Rock Island-Southern Pacific Train Station (built 1926, restored 2011)
• Odeon Theatre (built 1937, still operating)
• Crescent Creamery (vacant)
• Masonic Temple (still operating)
• Princess Theater (under renovation)

Also located in the downtown area are the concrete arches that once surrounded the Hotel Vorenburg, which was demolished in the 1970s after being damaged by fire. The Federal Building, commonly known as Sands-Dorsey Drug, was damaged by two fires before finally being demolished in 2015. The location is now a park.
