Hull Grammar School was a secondary school in Hull, England, founded around 1330 and endowed in 1479 by the prelate John Alcock. In 1988, as part of a restructure by the Local Education Authority which saw the school lose its sixth form, the site was renamed William Gee School for Boys. In 2001 the latter merged with the girls-only Amy Johnson High School as Endeavour High School, before closing permanently in 2015.
