The Alexander Dennis Enviro500 (previously known as the TransBus Enviro500) is a three-axle double-decker bus built by Alexander Dennis (formerly by TransBus International) in the United Kingdom. It was unveiled in 2002 and is one of the Enviro-series bus models made by TransBus/Alexander Dennis. The bus was sold on diesel or hybrid-electric powertrains and on Volvo chassis as a bodywork.

In 2014, the Enviro500 was superseded by the new Alexander Dennis Enviro500 MMC.
