Granville Island is a peninsula and shopping district in the Fairview neighbourhood of Vancouver, British Columbia, Canada, across False Creek from Downtown Vancouver, under the south end of the Granville Street Bridge. Formerly an industrial manufacturing area, it was named after Granville Leveson-Gower, 2nd Earl Granville.

The area is managed by the Canada Mortgage and Housing Corporation and includes a public market, restaurants, a marina, a hotel, the False Creek Community Centre, numerous artists' studios and workshops, and various performing arts theatres, including the Arts Club Theatre Company and Carousel Theatre.

It was the location for the finale of the film Mission: Impossible – Ghost Protocol (2011). The Great Canadian Pottery Throw Down, first broadcast in 2024, was filmed in the area.

The Vancouver International Children's Festival, the Vancouver Fringe Festival, and the Vancouver Writers Fest are held there, as are concert series of the Vancouver International Jazz Festival.

False Creek Ferries and Aquabus provide ferry service from Granville Island to Downtown Vancouver, Yaletown, False Creek, the West End, and Vanier Park. Other water transportation options include a water taxi service to Bowen Island provided by English Bay Launch.

WESTCOAST Sightseeing and Vancouver Trolley Hop-On, Hop-Off services have stops there.

Between 1998 and 2011, the Vancouver Downtown Historic Railway operated between Granville Island and Science World. The streetcar is now permanently shut down.

The peninsula was originally used by the Musqueam and Squamish peoples as a fishing area. A village was established in the area named sən̓aʔqʷ in the Hun'qumi'num language and Sen̓áḵw in the Squamish language.
