Lance Anthony O'Sullivan (born August 28, 1963 in New Zealand) was one of New Zealand's best-known jockeys, now retired.
He won a record number of races totalling 2479, mainly in the 1980s including the 1989 Japan Cup on champion mare Horlicks, which broke the world record over 2400m. He was also jockey of the unfortunate Waverley Star in the 1986 Cox Plate second to Bonecrusher, called the "Race of the Century."
In 2006, Lance O'Sullivan was part of the inaugural class inducted in the New Zealand Racing Hall of Fame.
