Alexander Dennis Limited (commonly abbreviated as ADL) is a British bus manufacturer headquartered in Guildford, Surrey, England. The company produces a range of public transport vehicles, including single-decker, double-decker, and hybrid buses, as well as coaches and low-floor buses for urban and intercity services.
History
The origins of Alexander Dennis trace back to the merger of two historic British bus-building firms: Walter Alexander Coachbuilders, founded in 1910 in Falkirk, Scotland, and Dennis Group, which had been producing commercial vehicles since 1900. In 2004, the two companies combined to form Alexander Dennis, consolidating their expertise in chassis and bodywork production.

Key product lines include:
- Enviro200 – a single-decker bus available in diesel, hybrid, and fully electric variants.
- Enviro400 – a double-decker bus, also offered in diesel, hybrid, and electric (Enviro400EV) versions.
- Enviro500 – a tri-axle double-decker model primarily targeted at high‑capacity markets such as Hong Kong and North America.
- ADL Eagle – a coach chassis introduced in the 2010s for long‑distance and tour operations.
