The Volvo B10M was a mid-engined city bus and coach chassis manufactured by Volvo between 1978 and 2003. It succeeded the B58 and was equipped with the same 9.6-litre horizontally mounted Volvo diesel engine mounted under the floor behind the front axle. An articulated version under the model name Volvo B10MA was also offered, as was a semi-integral version known as the C10M, with the engine in the middle of the chassis.

Designed as a successor to the Volvo B58, a large portion of B10M chassis were built in Sweden, but some were built in other countries, like England and Brazil.
The B10M was one of the best-selling chassis in the United Kingdom throughout the 1980s and 1990s. Having originally been produced only as a coach chassis, the B10M was made available as a city bus, in which form it was also very popular.
It was available as B10M-46, B10M-50, B10M-55, B10M-60, B10M-62, B10M-65 and B10M-70, where the number represents the wheelbase in decimetres. Many bodybuilders did however shorten or extend the chassis to fit their needs. No later than 1981 a tri-axle chassis was introduced, available as B10M-50B, B10M-55B, B10M-60B, B10M-65B and B10M-70B, with some bodybuilders extending them up to 7.25 metres wheelbase.
A double-decker version of the B10M was developed for Strathclyde PTE in 1981. It was launched in early 1982, with a downrated engine from the coach, and was named Citybus (also known unofficially as B10MD or D10M). Most early examples were bodied by Alexander Coachbuilders, who provided a modified version - common to all Volvo double-deck chassis bodied by the company after 1980 - of their popular and attractive R type bodywork. Eastern Scottish and Fife Scottish bought many of these early versions in 1985-1987. Two were exported in 1984, one of them to Singapore Bus Service and the other to Kowloon Motor Bus, but was destroyed by fire in 1988. The Citybus lasted until the end of B10M production but fell out of favour after Volvo re-engineered the Leyland Olympian as the Volvo Olympian in 1993.
