Glenna Collett Vare (June 20, 1903 – February 3, 1989) was an American Hall of Fame golfing champion whom the Hall calls the greatest female golfer of her day, and who dominated American women's golf in the 1920s.

Born in New Haven, Connecticut, Glenna Collett was raised in Providence, Rhode Island by athletic-minded parents and at a young age was involved in sports such as swimming and diving. At age 14 she took up the game of golf, and within two years had developed her skills to the point where she competed in the 1919 U.S. Women's Amateur, and won her first-round match. Two years later at age 18, she was the Championship medallist for shooting the lowest qualifying score.

In the pre-professional era, the U.S. Women's Amateur was the most prestigious event in the country. Her strength was off the tee. Collett was a student of golf instructor Ernest Jones.

While setting a new single-round scoring record, in 1922 Glenna Collett claimed her first of six U.S. championships. The following year she was upset in the third round, but went north to win the Canadian Women's Amateur. In 1924 Glenna Collett achieved the most remarkable record in golfing history, both female and male. Despite setting a new new single-round qualifying scoring record, Collett lost by a fluke in the semifinal of the 1924 U.S. Women's Amateur when on the 19th hole, Mary Browne's ball caromed off hers and into the cup. However, that would be her only loss in a year where she won an astonishing 59 out of 60 matches, including her second consecutive Canadian championship.
