David Foster OAM (born 20 March 1957) is an Australian world champion woodchopper, and Tasmanian community figure. He has held the World Woodchopping Championship title for 21 consecutive years, and is one of Australia's most successful athletes and possibly the only athlete in any sport in the world to win over 1,000 titles.

Foster is often joined in his charitable quests by the Launceston cricketer David Boon. Foster has received several awards for his cultural, charitable and community activities. These include being awarded an Order of Australia Medal, a commendation from the then Governor of Tasmania Sir Phillip Bennett and an Anzac Medal for services to the community.

He also received a Tasmanian of the Year award in 1995, and was appointed a director of the National Australia Day Council in 1998. In 2020, he was inducted into the Sport Australia Hall of Fame.
