John Stuart Stillings (born July 23, 1955) is an American former competitive rower and Olympic silver medalist.

Stillings was the coxswain of the U.S. men’s four with coxswain that won the silver medal in the men's coxed fours competition at the 1984 Summer Olympics in Los Angeles with Edward Ives, Thomas Kiefer, Michael Bach, and Gregory Springer.

One of the most successful coxswains in University of Washington history, Stillings guided the Huskies to two collegiate National Championships and its first and only Henley Royal Regatta Grand Challenge Cup victory in 1977, where the collegiate team defeated a heavily favored British National team.

In a sport dominated by young athletes, Stillings accomplished a successful come-back to international rowing at the age of 48, winning the gold as coxswain of the U.S. men’s eight-oared crew at the 2003 Pan American Games in the Dominican Republic.

He is married to Olympic gold medalist and fellow University of Washington alumnus Betsy Beard-Stillings.
