The Dennis Domino was a step-entrance midibus chassis manufactured by Dennis in Guildford, England in 1984 and 1985. It was in essence, a scaled down single-decker version of the Dennis Dominator. Developed for intensive urban work, the Domino was fitted with Perkins T6.354.4 turbocharged engine, Maxwell automatic transmission, front radiator, full air suspension and power steering. It can be regarded as a predecessor of the successful Dennis Dart.

A midibus is a classification of single-decker minibuses which are generally larger than a traditional minibus but smaller than a full-size single decker and can be anywhere between 8 metres and 11 metres long. While used in many parts of the world, the midibus is perhaps most common in the United Kingdom, where operators have found them more economical, and to have a sufficient number of seats compared to full size single-decker buses.
