Kuchar was born in Winter Park, Florida. He graduated from Georgia Tech, where he was a two-time first-team All-American on the golf team. In 1997, he won the U.S. Amateur. He received the Fred Haskins award in 1998 as the nation's top collegiate golfer. He was the low amateur at both The Masters and U.S. Open in 1998. He turned pro in 2000.  

Kuchar's first win on the PGA Tour came at the 2002 Honda Classic; however, by 2006 he was on the Nationwide Tour after failing to earn enough money to qualify for the PGA Tour. He won the Nationwide Tour's 2006 Henrico County Open and finished 10th on the money list to earn his 2007 PGA Tour card. He retained his card in 2007 by finishing 115th on the money list and again in 2008 by finishing 70th.  

Seven years after his first PGA Tour win, Kuchar won for a second time during the 2009 Fall Series at the Turning Stone Resort Championship in a playoff over Vaughn Taylor.  

On August 15, 2010, Kuchar made the U.S. 2010 Ryder Cup team by earning enough points to take the 8th, and last position, awarded on points. At the time Kuchar led the PGA Tour in top-10 finishes for the year, but had not won a tournament in 2010. The winless streak ended at The Barclays on August 29, 2010, which was played at the Ridgewood Country Club in Paramus, New Jersey; Kuchar defeated Martin Laird on the first hole of a sudden death playoff.  

In February 2011, Kuchar reached the semi-finals of the WGC-Accenture Match Play Championship where he suffered a 6&5 defeat by eventual champion Luke Donald. In the 3rd place playoff match Kuchar defeated fellow American Bubba Watson, 2&1.
