London Buses route 81 is a Transport for London contracted bus route in London, England. Running between Hounslow and Slough, it is operated by London United.

The 1980s saw the introduction by London Regional Transport of route tenders, with route 81 the first route to be put out to tender. The contract for the route was awarded to Len Wright Travel, which later became London Buslines, and passed to them from London Buses on 13 July 1985.

Tendering saw the route move from Hounslow garage to Lampton (later Isleworth, then Southall) and revert to double deck, using yellow Daimler Fleetlines. These were replaced in 1987 by Leyland Lynxes. On 29 July 1995 the route was lost to Westlink and moved to Hounslow Heath garage using Optare Deltas.
