Falmer High School was a community mixed-sex non-denominational comprehensive school for pupils aged 11 to 16 in Brighton, East Sussex, England.

It was Westlain Grammar School and administered by the Brighton Education Committee.

It became a school many parents from Brighton suburbs tried to avoid in the 1980s, as it served the council estates along Lewes Road, with some parents even going to court to stop their children attending the school.

Falmer High School was closed on 31 August 2010, replaced by the Brighton Aldridge Community Academy on the same site, sponsored by Rod Aldridge.

At the time some of Brighton and Hove's schools were below average at GCSE, and Falmer High School was joint bottom with results below the government minimum with Portslade Community College.
