The Anti-Flirt Club was an American club active in Washington, D.C., during the early 1920s. The purpose of the club was to protect young women and girls who received unwelcome attention from men in automobiles and on street corners. The Anti-Flirt Club launched an "Anti-Flirt" week, which began on March 4, 1923.

A Washington Post article from February 28, 1923, titled "10 Girls Start War on Auto Invitation," laid out the problem: "Too many motorists are taking advantage of the precedent established during the war by offering to take young lady pedestrians in their cars, Miss Helen Brown, 639 Longfellow Street, declared yesterday." Brown, the secretary of the nascent Anti-Flirt club, warned that these men "don't all tender their invitations to save the girls a walk," and while there were "other varieties of flirts," motorists were the absolute worst.
Brown, along with the president—a Miss Alice Reighly of 1400 Harvard Street—made their plan of action known. On March 4, 1923, the first-ever Anti-Flirt Week (and only since) would commence.
