The Palestinian flag is a triband of black, white, and green from top to bottom, overlaid by a red triangle issuing from the hoist. This flag is derived from the Pan-Arab colors and it was first adopted on 28 May 1964 by the Palestine Liberation Organization. The flag day is celebrated on 30 September.
The flag is almost identical to that of the extinct Hashemite Kingdom of Hejaz and to that of the Ba'ath Party.
