George Stroumboulopoulos Tonight is a Canadian television talk show broadcast on CBC Television and hosted by George Stroumboulopoulos. Originally known as The Hour from 2005 to 2010, it first broadcast on 17 January 2005. The programme is currently initially broadcast on CBC Television at 7:00 p.m. local time.

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., 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's opening theme song is "The Good in Everyone" by Canadian rock band Sloan. It replaced the formerly used track, "Use It" from The New Pornographers at the start of the 2008 broadcast season.
