Peter Lawrence Lonard (born 17 July 1967) is an Australian professional golfer who plays mainly on the U.S. based PGA Tour. He credits fellow Australian Greg Norman as his inspiration.

Lonard was born at Epping, Sydney. He turned professional in 1989 and began his career on the PGA Tour of Australasia. He played on the European Tour in 1991 and 1992, where he had very moderate results. He was sidelined for nearly 18 months in 1993-94 after contracting Ross River Fever, a mosquito-carried virus which caused damage to his eyes. He worked as a club professional for three years before returning to tournament golf, topping the PGA Tour of Australasia Order of Merit in 1996/97. He returned to the European Tour in 1997 and has performed steadily with a best Order of Merit placing of 18th in 2002.

Lonard joined the United States based PGA Tour in 2002 and settled in well, winning over $1 million in his first season. He won the PGA Tour of Australasia's Order of Merit for a second time in 2003. His first win in the U.S. came at the 2005 MCI Heritage. He has featured in the top 50 of the Official World Golf Rankings.
