The flag of the U.S. state of Maine from 1901 to 1909 was the first official flag to be used to represent the state other than its militia; it was later replaced by a more standard military-style flag in 1909.
The flag has seen a revival of interest due to local Maine vexillologists advocating for its re-adoption and businesses selling reproductions of it. There has been a movement for Maine to readopt a version of this flag design since at least 1991, with an unsuccessful referendum on the issue having been held in November 2024.
