William Thomas "Billy" Andrade (born January 25, 1964) is an American golfer.
Andrade was born in Bristol, Rhode Island. He attended Wake Forest University where he helped lead the Demon Deacons to the 1986 NCAA Championship. He played on the U.S. team in the 1987 Walker Cup, and turned professional in the same year. He has four wins on the PGA Tour, including the 1991 Kemper Open and Buick Classic, the 1998 Canadian Open, and the 2000 Invensys Classic, which marked the debut of the Titleist Pro V1 golf ball, used by Andrade in the victory. He has been featured in the top 50 of the Official World Golf Rankings.
Andrade is also an active contributor to charity. He and fellow PGA Tour professional Brad Faxon received the 1999 Charles Bartlett Award for their "unselfish contributions to society", and the American Heart Association's 2002 Gold Heart Award in recognition of their charity efforts. Also in 2002, Andrade and Faxon were named winners of the 2002 Ambassadors of Golf Award. Together, they run Billy Andrade/Brad Faxon Charities for Children, Inc., a non-profit organization that, as of 2005, has donated over $3 million to needy children in Rhode Island and southern Massachusetts. Since 1999, Andrade and Faxon have also served as hosts of the CVS Charity Classic, a golf tournament held at the Rhode Island Country Club each June, whose proceeds benefit the two players' charity.
