The flag of the Commonwealth of Massachusetts was adopted on March 18, 1908 and has only been changed once in 1971 with the removal of the reverse side. The flag features the state seal on a white field. The state currently has three official flags: a state flag, a governor's flag, and a "naval and maritime flag" (despite it no longer having its own naval militia).
With Florida, it is one of only two state flags to prominently feature a Native American in its heraldry. In 2001, a survey conducted by the North American Vexillological Association (NAVA) placed Massachusetts's state flag 38th in design quality out of 72 flags (U.S. state, U.S. territorial and Canadian provincial).
