The 1921 Women's Olympiad () was the first international women's sports event, a 5-day multi-sport event organised by Alice Milliat and held on 24–31 March 1921 in Monte Carlo at the International Sporting Club of Monaco. It was the first of three Women's Olympiads or "Monte Carlo Games" held annually at the venue, and the forerunner of the quadrennial Women's World Games, organised in 1922–34 by the International Women's Sports Federation founded by Milliat later in 1921.
