The Dennis Javelin (later known as the TransBus Javelin/Alexander Dennis Javelin) is an underfloor-engined bus and coach chassis originally built by Dennis (now by Alexander Dennis) in the United Kingdom. It was unveiled in 1986 and acted more or less as a modern replacement for the discontinued Bedford Y-series. It also supplanted the heavier Dennis Dorchester.
While proving a success, it has never matched its nearest rival, the likewise heavier Volvo B10M, but has had much more success than Dennis's previous coaching industry attempts: The Falcon V, the Lancet and Dorchester.
