Josef Stalder (6 February 1919 – 2 March 1991) was a Swiss gymnast and Olympic champion.
He competed at the 1948 Summer Olympics in London, where he received a gold medal on the horizontal bar, a silver medal in team combined exercises, and a bronze medal on the parallel bars.
He also won four medals at the 1952 Summer Olympics in Helsinki.
He was the originator and namesake of stalder circles, now a common skill on both the horizontal bar and the uneven bars.
