Jesus Green Swimming Pool is a lido situated on Jesus Green in Cambridge, England. Opened in 1923, it is one of the few remaining examples of the lidos built across the country in the 1920s — open air pools with space for activities other than swimming. Unusually, the pool is significantly longer than it is wide — this was a design idea to mimic swimming in the nearby river. It opens for public bathing between May and September every year. There is a much smaller outdoor pool upstream of the city centre at Sheep's Green, and swimming in the Cam remains popular near Grantchester.
