Doug Frost (born on November 11, 1943 in Orange, New South Wales) is an Australian swimming coach, perhaps best known as the coach of Ian Thorpe. He has been made an "Honor of Life Member" of the Australian Swim Coaches Association and of the Padstow Swim Club, New South Wales.
Frost was a coach on the Australian national teams for the 1995, 1997 and 1999 Pan-Pacific Games; the 1998 Swimming World Championship and Commonwealth Games teams and the 2000 Sydney Olympic Games team. He has been a director at the Australian Swim Coaches Association since 1989 and at the Doug Frost Swim School since 1978. After Thorpe controversially changed coaches, Frost left the Sutherland club to start afresh in Southport, Queensland. In May 2005, he was appointed the head coach of the swimming program at the Australian Institute of Sport.
