Stacy Prammanasudh (born September 23, 1979) is a Thai American golfer who plays on the LPGA Tour.
Stacy was born in Enid, Oklahoma to an American mother and a native Thai father who immigrated to the United States from Thailand. She was raised in Oklahoma, and attended the University of Tulsa where she won the Stanford Pepsi Intercollegiate from 1999 to 2001 and was a three-year Academic All-American, from 2000 through 2002. Prammanasudh was also a First-Team All-American from 1999 through 2002. She was the recipient of the Edith Cummings Munson Golf Award in 2001, which is given to one of the top female collegiate golfers who excels in academics. She finished her senior season ranked second in the nation and won 10 collegiate events throughout her college career. This is the second-most in the school's history, behind only Nancy Lopez’s 11 titles.
After graduating from college in June 2002, Prammanasudh joined the Futures Tour. In the fall of 2002, she competed in the LPGA Qualifying School, finishing tied for 24th, which earned her non-exempt status on the LPGA Tour for 2003. Competing on both the Futures Tour and LPGA Tour in 2003, Prammanasudh won two Futures events and finished in the top-10 in nine other events. She won the Futures Tour Player of the Year award, which earned her fully exempt status on the LPGA for 2004.
