George Stroumboulopoulos Tonight (originally known as The Hour) is a Canadian television talk show hosted by George Stroumboulopoulos that aired on CBC Television from 2005 to 2014.

As The Hour, the show was so named, as it was a daily one-hour program. For the show's seventh season, the show was renamed and shortened into a daily half-hour show, George Stroumboulopoulos Tonight, beginning September 20, 2010. In September 2011, the program was again extended to one hour with its current name. It returned to a half-hour for the 2012–13 season and moved to 7:00 p.m. (replacing Wheel of Fortune), along with a late-night encore that moved to 11:30 p.m. due to the expansion of late local news at several of the CBC's major market stations. The show concluded at the end of the 2013–2014 season as Stroumboulopoulos moved to Rogers Communications to host Hockey Night in Canada.

The show had two opening theme songs during its history. Its first was "Use It" by The New Pornographers, which was replaced by "The Good in Everyone" by Canadian rock band Sloan at the start of the 2008 broadcast season.
