Michael Thomas "Fluff" Cowan (born February 7, 1948) is a professional golf caddie on the PGA Tour. He is a 40-year tour veteran and one of its best-known caddies. Cowan has caddied for Ed Sabo (1976–1978), Peter Jacobsen (1978–1996), Tiger Woods (1996–1999), and Jim Furyk (1999–present). In 2003, he caddied for then-13-year-old amateur ladies' golfing sensation Michelle Wie for one tournament while Furyk was off due to injury. The Ryder Cup in 2012 was Cowan's eleventh, carrying for four different players: Jacobsen, Fred Couples, Woods, and Furyk. Cowan earned his nickname "Fluff" from his resemblance to professional golfer and broadcaster Steve Melnyk, also nicknamed "Fluff."
