Battersea Grammar School was a Voluntary-Controlled Secondary Grammar School in South London. It was established in Battersea in 1875 by the Sir Walter St John Trust and moved to larger premises in Streatham in 1936. The school closed when it was amalgamated with Rosa Bassett School, a grammar school for girls, in 1977 to create the new Furzedown Secondary School, a mixed comprehensive school in Tooting.
