The Sunday Night Sex Show was a live call-in Canadian television show which ran from 1996 to 2005. It aired on the W Network and was one of their most popular programs. Every week, callers would line up on the phone to talk to the host, Sue Johanson, about various topics from how to spice up one's sex life, to advice on how to select the right sex toy, to how to deal with various relationship issues.

For many years, reruns of the show ran on the Oxygen Network in the United States, but American viewers were frustrated that they couldn't call in during the live airing in Canada. Eventually, a U.S. version of the show, titled Talk Sex with Sue Johanson, was created.

Reasons for the Canadian cancellation were never given by either Johanson or the W Network. The U.S. show ended with the May 11, 2008 episode. Johanson was very emotional at the conclusion of the show and joined on stage by her supporting cast.

Before the television series aired, Johanson was host of a syndicated radio call-in show in Canada, which was initially titled Sex with Sue, and later became Sunday Night Sex Show. Johanson retained the latter title for her television series.
