The flag of Alberta is an official symbol of the province of Alberta, Canada. In 1968, the provincial legislature authorized the design of a flag, adopting it on 1 June 1968.
The flag has the proportions 1:2, with the provincial coat of arms in the centre of an ultramarine blue background. The shield's height is 7⁄11 that of the flag's height.
The provincial colours, adopted in 1984, are blue and gold (deep yellow); they are also referred to as "Alberta blue" and "Alberta gold", appearing on the flag/shield in the sky/background and wheat background, respectively.
In 2001, a survey conducted by the North American Vexillological Association (NAVA) placed the Alberta provincial flag 35th in design quality out of the 72 Canadian provincial, U.S. state, and U.S. territory flags ranked. Out of all Canadian flags, only Ontario and Manitoba ranked lower.
