The Napier Gazelle was a turboshaft engine manufactured by D. Napier & Son in the mid-1950s. In 1961 production was nominally transferred to a joint venture with Rolls-Royce called Napier Aero Engines Limited. But the venture closed two years later.

These helicopter engines were used on the Westland Wessex HAS 1 and HAS 3 (other versions of the Wessex had two Rolls-Royce Gnome engines) and the Bristol Belvedere (later Westland Belvedere) transport helicopter.

A preserved Napier Gazelle is on display at the Royal Air Force Museum London. A preserved Napier Gazelle from a Westland Wessex helicopter is on display at the Queensland Air Museum, Caloundra, Australia.
