The coat of arms of Saint Helena, part of the British Overseas Territory of Saint Helena, Ascension and Tristan da Cunha, was authorised on 30 January 1984.

The arms feature a shield, with the top third showing the national bird, the Saint Helena plover (Charadrius sanctaehelenae), known locally as the wirebird – stylized, but with its unmistakable head pattern.

The full coat of arms features, above the shield, a woman holding a cross and a flower.

The local two pound coin has the full coat of arms on its reverse.

The arms were also used by Ascension Island and Tristan da Cunha when they were dependencies of Saint Helena before 2009.
