Flag of Tristan da Cunha

The Flag of Tristan da Cunha was adopted on October 20, 2002 in a proclamation made by the Governor of Saint Helena under a Royal Warrant granted by Queen Elizabeth II. Prior to this, as a dependency of Saint Helena, Tristan da Cunha used the Flag of Saint Helena for official purposes.

The flag is a blue ensign design, defaced with the Coat of Arms of Tristan da Cunha- a Tristan longboat above a Naval Crown, with a central shield decorated with four yellow-nosed Albatrosses and flanked by two Tristan rock lobsters. Below this is a scroll with the territory's motto, "Our faith is our strength."

The designer is the prominent vexillologist Graham Bartram.
