Philip Arthur Cayzer OAM, (13 May 1922 – 15 July 2015) was an Australian national champion rower who won medals in the 1952 Summer Olympics and the 1950 British Empire Games.

He stroked the New South Wales representative eight in the King's Cup at the Interstate Regatta within the Australian Rowing Championships on five occasions from 1948 to 1954.

The New South Wales 1950 Kings Cup win also resulted in the opportunity to represent Australia and the crew travelled to the Canterbury Centennial Games and 1951 New Zealand Championships, defeating the University of California by a canvas in both races.

An all-New South Wales crew was selected to represent Australia at the 1952 Henley Royal Regatta and 1952 Helsinki Olympics.

He coached the coxed four of Alf Duval, Alan Grover, Mick Allan, John Campbell and Gary Herford selected to compete at Tokyo 1964.
