KVOS-TV (channel 12) is a television station licensed to Bellingham, Washington, United States, serving the Seattle–Tacoma market as an affiliate of the Spanish-language network Univision. It is owned by Weigel Broadcasting alongside Seattle-licensed MeTV owned-and-operated station KFFV, channel 44 (which KVOS simulcasts on its third digital subchannel). Its other subchannels carry Weigel's other diginet concepts. Though it now functions as a Seattle-market station, for much of its history it primarily served an audience in southwestern British Columbia, Canada, including Vancouver and Victoria.

KVOS-TV's transmitter is situated atop Mount Constitution on Orcas Island in the San Juan Islands, at an altitude of 2,621 feet (799 m) above the adjacent terrain. The station's signal is very well received throughout the British Columbia Lower Mainland, southern Vancouver Island, and much of northwest Washington. KVOS-TV's original studios were located on Ellis Street in Bellingham. However, with the sale of KVOS-TV to OTA Broadcasting in 2010, the Bellingham facility was closed and the station currently shares studios with KFFV on Third Avenue South in Seattle. KVOS-TV at one time maintained offices in Burnaby, British Columbia, and before that on West 7th Avenue in Vancouver, but no longer has a physical presence in the Vancouver area.

KVOS signed on June 3, 1953; owned by Bellingham businessman Rogan Jones along with KVOS radio (AM 790, now KGMI). Jones had owned the radio station since 1928, and was best known for being the focus of a case that established broadcasters' right to the same news reports as newspapers. Its first broadcast was a kinescope of Queen Elizabeth II's coronation, which took place the previous day. Since Canada had no television stations operating west of Ontario at that point (it was not until that December that Vancouver would get a locally-operated TV station of their own in CBC outlet CBUT), the British government flew film of the BBC's coverage to Vancouver, where the Mounties escorted it to the border. The Washington State Patrol then drove the film to Bellingham. The station's original slogan was "Your Peace Arch Station, serving Northwest Washington and British Columbia."

KVOS initially experienced financial trouble, despite Jones thinking that he could successfully support a television station in a city the size of Bellingham. He built a powerful transmitter on Orcas Island in hopes of reaching Seattle, but even with increased power, it did not cover enough of the Seattle area to solve the problem. For a time, the revenues from his radio station were all that kept channel 12 afloat. In 1955, Jones, realizing that most of his audience was across the border, incorporated KVOS in Canada, establishing a subsidiary company in Vancouver. The subsidiary, KVOS-TV Limited, brought in revenue for the station by allowing many Vancouver-area businesses to buy advertising time on the station. KVOS-TV continued to broadcast from Bellingham, with much of its audience based in southwestern British Columbia.

After just nine years of owning KVOS-TV, in 1962 Jones sold the station to Miami-based Wometco Enterprises.

Prior to the advent of Canadian content regulations in the early 1970s, Canadian television stations typically spent so little money on domestic television production that KVOS's Vancouver production office was actually one of the largest Canadian production studios anywhere in the entire country, investing most prominently in television documentaries through its Canawest Film Studios division and employing more Canadian writers, actors, artists and musicians than any other media organization in Canada besides the CBC, according to Vancouver MP Simma Holt.

The station was further damaged by a 1976 change in Canadian tax law, by which Canadian companies could no longer write off advertising purchased on American television stations as a tax deduction. In its efforts to stop the change, the station had proposed that it be granted an exemption on the condition that it then return $2 million per year back to Canadian television production; its proposal did not succeed, but the station survived the hit by closing its Canadian production office and reducing its advertising rates to offset the tax increase that its advertisers would have to pay. Even into the 1990s, the station was still sometimes criticized in CRTC licensing hearings pertaining to the Vancouver television market for purportedly draining advertising revenue from the Vancouver stations; CKVU-TV president Daryl Duke once even went so far as to compare KVOS to smallpox.

Dave Mintz, who had been a minority investor in the station since 1955 and president of the station since 1961, left the station in 1979 to become president of Canada's fledgling Global Television Network. Although American by birth, due to the importance of the Vancouver operations to the station, Mintz was residing full-time in Vancouver by the time he took the Global job.
