The River Chess is a chalk stream that rises near Chesham in the Chiltern Hills in England, and flows for 11 miles (18 km) through Buckinghamshire and Hertfordshire to its confluence with the River Colne in Rickmansworth. The Chess, along with the Colne and Gade, gives rise to the name of the district of Three Rivers.
