Timothy John Willoughby (24 June 1954 – 9 January 2008) was an Australian rower, yachtsman and stock broker who won a bronze medal as part of the men's eights team at the 1984 Summer Olympics in Los Angeles.
Born in Adelaide, South Australia in 1954, Willoughby first began to show promise as a rower whilst at St Mark's College at the University of Adelaide, where he was a boat captain in the Adelaide University Boat Club. He competed in two Olympic Games: 1980 in Moscow and 1984 in Los Angeles. As a member of the men's eights team, Willoughby received a bronze medal when Australia placed third in the final with a time of 5:43.40.
Subsequent to his win in Los Angeles, Willoughby was a crew member of the Australian yacht Kookaburra III, which attempted to defend the America's Cup in 1987, but was defeated by the American yacht Stars & Stripes. He remained in Perth following the America's Cup, and became president of the WA Olympic Council and of the Olympians Club of WA, representing Western Australia to the Australian Olympic Committee.
Willoughby spent twenty years as a stock broker for the Goldman Sachs JBWere investment bank. Having left Goldman Sachs in late 2007, Willoughby was due to start work at the firm of Citi Smith Barney on 10 January 2008, but died suddenly on 9 January 2008 after suffering a heart attack on board a flight from the United States to Singapore, returning home from a family holiday in New Mexico.
