Flasher is a city in Morton County, North Dakota in the United States. It is part of the "Bismarck, ND Metropolitan Statistical Area" or "Bismarck-Mandan". The population was 232 at the 2010 census. Flasher was founded in 1902.
Flasher was founded by William H. Brown who plotted the town site and had the town surveyed into lots. He tried to name the town "Iowa City", but the postal department would no longer allow a state's name to be in the name of a city. So he decided to name it "Flasher" after his niece Mable Flasher Vrooman. Flasher started a newspaper in 1903, "The Flasher Hustler". The city was surging in growth and Flasher survived The Dust Bowl unlike most farming communities. The city flooded in 1943 in the spring time. The Heart River was overflowing and as of today some people continue to call the river "Heartless" because of the damage it had caused to the little town.
