The AgustaWestland CH-149 Cormorant is the Canadian Forces designation for the AgustaWestland AW101, a helicopter used for air-sea rescue in Canada. Developed from AgustaWestland in Italy, the CH-149 is a medium-lift helicopter for military applications.

The AgustaWestland AW101 is a medium-lift helicopter in military and civil use. First flown in 1987, it was developed by a joint venture between Westland Helicopters in the United Kingdom and Agusta in Italy in response to national requirements for a modern naval utility helicopter. Several operators, including the armed forces of Britain, Denmark, and Portugal, use the name Merlin for their AW101 aircraft. It is manufactured at factories in Yeovil, England, and Vergiate, Italy. Licensed assembly work has also taken place in Japan and the United States.
