Constant ("Stan") Ockers (3 February 1920 in Borgerhout – 1 October 1956 in Antwerp) was a Belgian professional racing cyclist.
He was runner-up in the Tour de France in 1950 and 1952, and the best sprinter in that race in 1955 and 1956. In 1955 he won the Classic "Ardennes double" by winning La Flèche Wallonne and the Liège–Bastogne–Liège in the same year. At this time the races were run on successive days as "Le Weekend Ardennais". He also won the World Cycling Championship that year.
Stan Ockers died after crashing during a track race in Antwerp in 1956. A year later a monument was built in Les Forges, Sprimont, in the south of Belgium.
