Denman Island is one of the Northern Gulf Islands and part of the Comox Valley Regional District of British Columbia, Canada, and is home to a small community of 1,016 year-round residents (2001 census). Regular ferry service links Denman Island to both Hornby Island from Gravelly Bay on the east side of Denman and across Baynes Sound to Buckley Bay on Vancouver Island on the west side. Denman Island has long been a haven for people escaping from busy urban centres. Downtown Denman consists of one general store (containing the gas station and government liquor store), post office, a natural foods store, hardware store, bookstore, dental bus (shared with Hornby two weeks a month), craft stores, a bakery/cafe, two real estate offices, an insurance brokerage, two community halls, the Dora Drinkwater Volunteer Library, a community school, and the museum. It is famous for its summer dances, the Martini Lounge Cabaret, quiet roads, and beautiful scenery. Many artists have made Denman Island their home for decades, and as a result there is a thriving local artistic community. The island has a land area of 51.03 square kilometres (19.70 sq mi), and is similar in size and shape to the island of Manhattan.
Denman and Hornby Islands are two outposts that have been described, with some justification, as the "undiscovered Gulf Islands." Big-name celebrities have recently bought property here, complementing a population made up of farmers, baby-boomers, artists, craftspeople and a laid-back mishmash of alternative types
