Ruislip Lido is a reservoir and artificial beach in Ruislip, within the London Borough of Hillingdon, England, situated between Ruislip Common, Ruislip Woods, and Poor's Field.
Originally created as a feeder basin for the Grand Junction Canal in 1811, the reservoir was reopened in 1933 as a lido, with facilities for swimming and boating.
During World War Two the lido was secretly used by the Royal Air Force to train aircrew based at R.A.F. Northolt and R.A.F. Uxbridge in water survival methods.
