The River Lee or River Lea (both spellings are in general use) is a river in England. It originates at Luton in the chalk beds of the northeast Chiltern Hills and flows generally east and then south to London where it meets the River Thames - the last section being known as Bow Creek.

The spelling Lea is predominant west (upstream) of Hertford, but both spellings are used from Hertford to the River Thames; the Lee Navigation was established by Acts of Parliament and should be so spelt.

Once an important commercial waterway, certain sections were canalised as part of the River Lee Navigation. Another artificial channel, the New River was constructed to take clean water to London from the Lee and its catchment areas and bypass the polluting industries that had developed in its downstream reaches. It rises just west of Luton, and flows through (or by) Luton, Harpenden, Welwyn Garden City, Hertford, Ware, Hoddesdon, Cheshunt, Upper Clapton, Hackney Wick (where it causes Hackney Marsh), Stratford, Bromley-by-Bow, Canning Town and finally Leamouth where it meets the River Thames (as Bow Creek).

Inside Greater London, the Lee passes a series of reservoirs: King George's Reservoir at Brimsdown, William Girling Reservoir at Edmonton and the Banbury Reservoir at Tottenham. At Tottenham Hale there is a connected set of reservoirs; Lockwood Reservoir, High Maynard Reservoir, Low Maynard Reservoir, Walthamstow Reservoirs and Warwick Reservoirs. It also passes the Three Mills.
