Hilary Lunke (born Hilary Homeyer on June 7, 1979) is an American professional golfer.

Homeyer was born in Edina, Minnesota. She attended Stanford University and became a member of the LPGA Tour in 2002. On July 7, 2003, Lunke defeated Kelly Robbins and Angela Stanford in an 18-hole playoff to win the U.S. Women's Open for her first and only LPGA win. Lunke was also the first player to win the U.S. Open after advancing through local and sectional qualifying.

Lunke's husband, Tylar, was her caddie on that July day. They married on November 2, 2002. Lunke gave birth to her first child, Greta Elin, in November 2007. She had her second child, daughter Marin, in October 2009.

Lunke joined the LPGA Player Executive Committee in 2006, and was selected vice president in 2007 and president in 2008. At the end of 2008, she was named the winner of the William and Mousie Powell Award, given to an LPGA member "who, in the opinion of her playing peers, by her behavior and deeds, best exemplifies the spirits, ideals and values of the LPGA."

Lunke retired at the end of the 2008 season.
