Isabel Bassett (born 1939) is a Canadian broadcaster and former politician. She is currently the chair and CEO of TVOntario, Ontario's provincial public television network, a position she has held since 1999. She has been a controversial figure at times, but is also a highly regarded pioneer in Canadian broadcasting.

Bassett first entered Canadian public life as a journalist for the Toronto Telegram in the 1960s. She later joined CTV, where she became a prominent reporter and documentary producer, including a stint with W5, after marrying Baton Broadcasting owner John Bassett in 1970. Although her documentary work for CTV won numerous awards, she was sometimes accused of having been given her position solely because she was married to the owner.

In the federal election of 1993, Bassett ran as a Progressive Conservative candidate in the Toronto riding of St. Paul's. She lost to Liberal Barry Campbell by over 15,000 votes.

Bassett was elected to the Legislative Assembly of Ontario in the provincial election of 1995, defeating Liberal Carolyn Bennett (later a federal MP) by about 3,500 votes. She served as the Progressive Conservative MPP for St. Andrew—St. Patrick for the next four years, and on October 10, 1997 was appointed Minister of Citizenship, Culture and Recreation in the government of Mike Harris. Despite the Harris government's right-wing reputation, Bassett is actually a Red Tory and was one of the most socially progressive members of the Harris cabinet.

John Bassett died in 1998, and Isabel subsequently began a relationship with cabinet colleague Ernie Eves.

In the 1999 provincial election, Bassett was defeated in the new provincial riding of St. Paul's by Liberal candidate Michael Bryant. She was one of several Toronto Progressive Conservatives defeated due to the unpopularity of Harris' government in the city. The Conservatives won the provincial election, however, and Harris subsequently appointed Bassett head of TVOntario. Her mandate was to refocus the network squarely on educational programming; however, Bassett successfully found ways to ensure that the network's most popular non-educational programs, such as Saturday Night at the Movies and Studio 2, could continue to air.

Bassett's position again became controversial when Eves became Premier of Ontario in 2002, with media critics noting the potential conflict of interest inherent in Bassett remaining as head of TVOntario while simultaneously in a common law relationship with the provincial premier. Bassett was popular within TVOntario, however, and the controversy soon subsided. She still serves as head of TVOntario in 2005, more than a year after the Eves government was defeated by Dalton McGuinty's Liberals.

Bassett has also authored a number of books on the political, social and historical achievements of Canadian women.
