George Brown (5 November 1906 – 7 July 1937) was an Irish born communist activist and trade unionist who was based in Manchester, England for most of his life.

He was a brigadista in the International Brigades fighting on the Republican side in the Spanish Civil War and was killed in the Battle of Brunete in 1937.

His parents were Francis Brown and Mary (née Lackey) who came home to Inistioge specifically for George to be born there.

He was heavily influenced by the harsh conditions for workers in Britain at the time and soon joined the trade union movement.

The 1926 British General Strike was a turning point in his life and his experience there led to him joining the Communist Party of Great Britain.
