Marion Miley (February 18, 1914 – September 28, 1941) was an American amateur golfer. Active in the 1930s, she won dozens of amateur tournaments and was ranked as high as #1 in the United States. She was noted by the press as being one of the most photogenic golfers in the world and received international acclaim from her successes both nationally and abroad, bringing attention to the sport of women's golf in the era prior to the establishment of the LPGA. She was murdered in 1941 during a robbery of the country club where she and her mother lived, dying at the age of 27; her mother also died as a result of the crime.
