The men's 1500 metre freestyle event at the 1952 Olympic Games took place between 31 July and 2 August, at the Swimming Stadium. This swimming event used freestyle swimming, which means that the method of the stroke is not regulated (unlike backstroke, breaststroke, and butterfly events). 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 consists of 30 lengths of the pool.
