The flag of Jersey is composed of a red saltire on a white field. In the upper quadrant the badge of Jersey surmounted by a yellow “Plantagenet crown“. The flag was adopted by the States of Jersey on 12 June 1979, proclaimed by Queen Elizabeth II on 10 December 1980 and first officially hoisted on 7 April 1981.

The flag of Jersey has been decreed by the Sovereign for use in the Bailiwick of Jersey as the Island’s flag. The Union Flag may also be flown, but precedence should be given to the flag of Jersey. The Bailiff of Jersey requests the flying of the flag of Jersey on government buildings on a list of official flag days when flags are flown from the seat of the judiciary and legislature; individuals are encouraged, but not obliged, to observe official flag days also.
