The Dennis Trident 2 is a 2-axle low-floor double-decker bus chassis originally manufactured by Dennis, which was unveiled in 1997 and replaced the Dennis Arrow. It was built by TransBus after Dennis was incorporated into the group in 2001 (the Dennis brand name was once dropped). From 2004, it was built by Alexander Dennis. The Dennis Trident 2 can be built as either a closed top bus or an open-top bus.

The Trident 2 chassis features a transversely mounted engine on the right side, with the radiator mounted on the left side of the engine compartment. It could be fitted with C-series Euro II engine (later Cummins ISCe Euro III engine), coupled to Voith DIWA or ZF Ecomat gearbox. It was available with Alexander ALX400, Plaxton President and East Lancs Lolyne/Myllennium Lolyne bodywork.

In the first few years of production, the Trident 2 was popular with a large number sold to large bus operators such as Stagecoach, FirstGroup, Travel West Midlands and Lothian Buses. Some Tridents were exported to Ireland (for Dublin Bus) and Spain (for sightseeing operations in Barcelona and Madrid). But later, due to increased competition after the launch of Scania OmniDekka and TransBus being put into administration, the sales of Trident 2 dropped significantly, leaving Stagecoach as its major buyer.
