Stephen J. Flesch (born May 23, 1967) is an American professional golfer and TV golf analyst.
Flesch finished in the top ten on the Asia Golf Circuit Order of Merit in 1993, 1994 and 1996. He won the 1997 NIKE Tour Championship to earn a PGA Tour card for the following season, only the second left-hander to win on what is now the Korn Ferry Tour. His first win on the PGA Tour was the 2003 HP Classic of New Orleans, but is probably best known for his come-from-behind victory at the 2004 Bank of America Colonial in Fort Worth, Texas. He has been featured in the top 50 of the Official World Golf Rankings, reaching a career high of 22nd in 2004.
