Swimming at the 1960 Summer Olympics – Women's 100 metre freestyle
The women's 100 metre freestyle event at the 1960 Olympic Games took place between August 26 and 29. This swimming event used freestyle swimming, which means that the method of the stroke is not regulated. Nearly all swimmers use the front crawl or a variant of that stroke. Because an Olympic-size swimming pool is 50 metres long, this race consisted of two lengths of the pool.
Competition format
The competition used a three-round format. The advancement rule followed the format introduced in 1952. A swimmer's place in the heat was not used to determine advancement; instead, the fastest times from across all heats in a round were used. There were 7 heats of between 6 and 8 swimmers each. The top 24 swimmers advanced to the semifinals. There were 3 semifinals of 8 swimmers each. The top 8 swimmers advanced to the final. Swim-offs were used as necessary to break ties.Results
