Tubridy Tonight is a talk show hosted by Ryan Tubridy that aired on RTÉ One for five seasons between 2004 and 2009. The programme featured guest interviews (usually three per show), audience participation and live music from both a guest music group and the house band. Tubridy Tonight aired every Saturday night, except during the summer months, directly after the main evening news. The show's house musical act was Clint Velour and the Camembert Quartet.

Tubridy Tonight was the first successful Saturday night chat show to be broadcast by RTÉ since the ending of Kenny Live in 1999. The programme had regular viewing figures of 450,000, however, the show also regularly fell victim to so-called "Saturday Night Syndrome", with The Late Late Show, broadcast on Friday nights, frequently featuring supposedly better guests. In 2009 Tubridy Tonight came to an end when RTÉ announced that Tubridy would succeed Pat Kenny as host of The Late Late Show for the following series, with the presenter describing Tubridy Tonight as "quite the odyssey".
