Mount Gravatt is the name of both a major suburb of Brisbane, Queensland, Australia and a prominent hill in this suburb. The suburb is situated in the south-east of the city and was one of Brisbane's largest. This was before it was divided into Mount Gravatt East, Upper Mount Gravatt and Mount Gravatt South; the last being changed to Wishart in the early 1990s. At the 2011 Australian Census the suburb recorded a population of 3,238
Between 1953 and 1969 electric trams ran from the suburb into Brisbane's Central Business District (CBD) along Logan Road. As Mount Gravatt was the end of the line, part of the area was known locally as "The Terminus". Since then public transport has been provided by buses operated by Brisbane Transport and a local bus company the Mount Gravatt Bus Service. The South East Busway is connected by a service from Mount Gravatt Central to the Busway terminal at Griffith University.

The people of greater Mount Gravatt are represented by the State parliamentary seats of Mansfield and Greenslopes and the federal seats of Bonner, Griffith and Moreton.

The Mount Gravatt Showgrounds are an important centre for cultural and community activities and the site of the annual Mount Gravatt Show, an agricultural fair. The grounds are positioned on Logan Road, opposite the mega-church, Hillsong Brisbane Campus (formerly known as Garden City Christian Church).
