Cayman's national song, "Beloved Isle Cayman", was written by the late Mrs. Leila Ross Shier in 1930. It was widely considered as the unofficial national song for many years and became the official national song when the Cayman Islands Coat of Arms, Flag and National Song Law was passed in 1993. As a British Overseas Territory, the national anthem is "God Save the Queen".
