Cock Beck is a stream in the outlying areas of East Leeds, West Yorkshire, England, which runs from its source due to a runoff north-west of Whinmoor, skirting east of Swarcliffe and Manston (where a public house has been named 'The Cock Beck'), past Pendas Fields, Scholes, Barwick-in-Elmet, Aberford, Towton, Stutton, and Tadcaster, where it flows into the River Wharfe.
