Arda was the wife of King Baldwin I of Jerusalem. She was the first Queen consort of the Kingdom of Jerusalem. Her name is unrecorded in contemporary sources, but since the 17th century she has been traditionally called Arda. She was the daughter of a minor Armenian noble. Baldwin married her in 1097 after the death of his first wife. In 1105 Baldwin had the marriage annulled, supposedly because Arda had been unfaithful, or because she had been raped by pirates on the way to Jerusalem.
