Sven Coomer (born 12 October 1940) is an Australian modern pentathlete. He competed at the 1956 Summer Olympics.^[1]

Coomer went on to study product design in Sweden, where he learned to ski and ski-race. He later worked as a ski racing coach, ski instructor and ski school director in the United States. That career led to a job designing ski boots for the Italian firm Nordica, and his designs were widely imitated by other factories.^[2]
