Thomas Dickson "Tommy" Armour III (born October 8, 1959) is an American professional golfer.
Armour first joined the PGA Tour in 1981 at the age of 21. He is considered to be a great ball striker, and much of his success depends on how well he putts. He has two career PGA Tour victories, winning the 1990 Phoenix Open and the 2003 Valero Texas Open. He currently holds the scoring record for best overall score on 72 holes (254), which he set during his Valero Texas Open victory in 2003.
Armour is the grandson of three-time major champion Tommy Armour. He lost his Tour card in 2006 due to an injury; however, he had a good 2007 season in the few events he was able to play, finishing 110th on the PGA Tour money list, earning his card for 2008. He finished his year with a win at the non-PGA Tour sponsored Callaway Golf Pebble Beach Invitational, winning $60,000. In 2008, he finished 62nd on the money list to retain his card for 2009 and was the first repeat champion at the Callaway Golf Pebble Beach Invitational.
