HMCS Okanagan (S74) was an Oberon-class submarine that served in the Canadian Forces (CF).

Okanagan was laid down on 25 March 1965 at Chatham Dockyard, Chatham, England and launched on 17 September 1966. She was commissioned into the CF on 22 June 1968 with pennant number 74.

In July 1973, Okanagan collided with the Royal Fleet Auxiliary vessel Grey Rover while exercising in British waters. Fortunately, there were no injuries to the submarine's crew.

Okanagan participated in the filming of the Japanese disaster film Fukkatsu no hi, released in 1980; one of her officers was given a small speaking role.

She was decommissioned from Maritime Command (MARCOM) on 14 September 1998. She had served her entire career with Maritime Forces Atlantic (MARLANT) in the North Atlantic.

In May 2005, the Halifax Chronicle-Herald announced that MARCOM was looking to sell Okanagan for scrap metal, along with three other Canadian Oberons laid up at CFB Halifax. MARCOM stated that the submarines were not in suitable condition to be used as museum ships and predicted that each submarine would sell for between C$50,000 and C$60,000.[1] Okanagan was towed to a scrapyard in Port Maitland, Ontario in August 2011.[2]
