Grosvenor Grammar School was founded in 1945 as Grosvenor High School, by the Belfast Corporation, to cope with the increase in demand for grammar-school education in the area. It was sited in Roden Street, off Grosvenor Road, and remained there until 1958, when the school moved to Cameronian Drive in the east of the city. In 2010, the school moved to its present location, Marina Park.
Its headmasters have been William Moles (1945–1972), Ken Reid (1972–1993), John Lockett (1993–2008), and R. S. McLoughlin (2008–2014). On 19 December 2014 Robin McLoughlin made his final speech at Grosvenor before moving on to Banbridge Academy, making way for the school's first headmistress, Dr Frances Vasey (2014−Present).
The area from which the school draws its pupils has expanded enormously over the years, to include greater Belfast and north and mid-Down. In order to avoid confusion with non-grammar 'high schools', the school changed its name in 1993 to Grosvenor Grammar School.
In rugby, the school has won the Ulster Schools Cup once (in 1983). Grosvenor has also experienced major successes in the Ulster School's Cup for football, with recent wins in 2016 as well as 2017, with their 1st XI seeing off St Columb's of Derry by 3-2.
Democratic Unionist politician Sammy Wilson MP MLA is a former economics teacher at the school. Michelle McIlveen MLA, also a Democratic Unionist, taught history and politics at the school. Willie Anderson (former Ireland rugby international) is a former PE teacher at Grosvenor.
Grosvenor also has two Irish cricket players working in the school, namely Kyle McCallan and Andrew White. Kyle took a job at Grosvenor just before he had to leave for the 2006 cricket world cup. Andrew joined the school in September 2007.
Nathan Connolly, lead guitarist of rock band Snow Patrol, is also a former pupil of the school. Also, George Best attended Grosvenor for a short period of time before transferring to a nearby high school.
