The Centre Cumbernauld (formerly Cumbernauld town centre and The Cumbernauld SHopping Centre) is the commercial centre of the new town of Cumbernauld, Scotland. It was designed in the 1950s—as what became known as a megastructure—to be a town centre consisting of "one huge multi-storey building," according to its preliminary planning report, housing shops, apartments, a hotel, ice rink, police station and other amenities. The building was designed to be expanded upon after its initial construction. Each time the building floorplan was modified the building was said to be in a new "phase", with Phase 1 being the original floorplan.

Phase 1 was completed between 1963 and 1967, and the centre was opened by Princess Margaret and Lord Snowdon in May 1967. It was expanded several times, including in 2007 by the addition of the Antonine Centre, a shopping centre that is linked to the older structure by walkways and lifts.

The development, promotion, and management of The Centre Cumbernauld was undertaken by the Cumbernauld Development Corporation (CDC), until the dissolution of the CDC by government order in 1996.

The facility has been subject to harsh criticism over the years. It was voted "Britain's most hated building" in 2005, in a poll organised by Channel 4's programme Demolition, and was twice named Scotland's worst town centre by the Carbuncle Awards. The brutalist structure was called "a rabbit warren on stilts" by the 2001 Carbuncle judging panel. The top section of the building has been dubbed by writers including author Caro Ramsay as the "Alien's Head", due to local people observing a resemblance to fictional character E.T.

In March 2022, North Lanarkshire Council announced plans to demolish the building.

Cumbernauld was designated as a New Town in December 1955 under the New Towns Act 1946 (9 & 10 Geo. 6. c. 68), as part of a plan to move 550,000 people out of Glasgow and into nearby planned or redeveloped towns to solve the city's overcrowding. The idea behind the Cumbernauld town centre was to create a singular megastructure, in the brutalist style, to "accommodate all the retail, municipal, and leisure needs" needs of a town of 50,000–80,000 people (although architecture historian John R. Gold notes that the term megastructure was first coined in 1964).

Regarded at the time as a "milestone in urban design," the town centre was intended to be surrounded by high-density housing without shops or other amenities, with each neighbourhood connected to the structure by pathways so that residents could easily walk there. This centralization of amenities was unlike other New Town developments, which typically built retail spaces within each new neighbourhood. Architectural critic Wolf von Eckardt wrote in Harper's in 1965:

Leonardo da Vinci, nearly five hundred years ago, envisioned a city where all the vehicles move underground, leaving man to move freely in the sun. Leonardo might also have sketched Cumbernauld's town center, a soaring citadel surrounded by meadow."
