William Timothy Britton (born November 13, 1955) is an American professional golfer who played on the PGA Tour for fifteen years during the 1980s and 1990s.

Britton was born and raised on Staten Island, New York, and attended Monsignor Farrell High School. He played college golf at Miami Dade College, winning the National Junior College Championship in 1975. He received an athletic scholarship to attend the University of Florida, where he played for coach Buster Bishop's Florida Gators men's golf team in National Collegiate Athletics Association (NCAA) competition in 1976 and 1977. Britton graduated from Florida with a bachelor's degree in health and human performance in 1979. He was mentored by Jim Albus, a club professional and six-time winner on the Champions Tour.

Britton is a two-time winner of the Metropolitan Amateur, and was the two-time defending champion when the tournament was held at Century Country Club in Purchase, New York, in 1977. He advanced to the quarterfinals at Century, and played Lou Mattiace, the father of future PGA Tour player Len Mattiace. In a memorable match, Mattiace dethroned the Staten Island native on the 18th green, 1-up.

Britton then turned professional in 1979 and joined the PGA Tour in 1980.

During his 15 years on the Tour, Britton won once and had 23 top-10 finishes. His best finishes in majors came in 1990: T-7 at The Masters and 4th in the PGA Championship.

After his years as a touring pro were over, Britton became a teaching pro and author in New Jersey. He has published articles for The Met Golfer, New Jersey Golfer and Sports Illustrated. He has been named one of the "Top Ten Teachers" in New Jersey by Golf Digest. He was New Jersey Section PGA's Player of the Year in 2002, and Senior Player of the Year in 2006. He has played in a limited number of Champions Tour events.
