Genevieve Hecker (1884 - July 29, 1960) was an American amateur golfer. A member of the Essex County Country Club in West Orange, New Jersey, she won New York City's Metropolitan Golf Championship in 1900, 1901, 1905, and 1906.
Hecker was born in 1884. In October 1901, she won the U.S. Women's Amateur at the Baltusrol Golf Club in Springfield Township, Union County, New Jersey. She also tied with Margaret Curtis and two others for the championship's lowest qualifying score. The following year she won the U.S. Amateur again on a course at The Country Club in Brookline, Massachusetts.
In 1903, Hecker married Charles T. Stout and in 1904 she published Golf for Women, the first book ever written exclusively for female golfers. The book included a chapter by Irish golfer Rhona Adair who won four straight Irish Ladies Close Championships and the 1900 and 1903 British Ladies Amateurs.
Hecker died on July 29, 1960.
