Prime Time is a current affairs programme noted for its in-depth analysis of political and other current events. It airs on RTÉ One on Monday at 10.30 & on Tuesday and Thursday nights following the RTÉ Nine O'Clock News.

Miriam O'Callaghan has been its main presenter for over fifteen years. O'Callaghan's fellow presenters are Claire Byrne and George Lee.

Prime Time has been broadcast on RTÉ One since 1992. Only one show per week is broadcast during the summer months. In January 2013, Pat Kenny's current affairs show The Frontline ended with its format and presenter subsumed into the Prime Time brand as part of a re-organisation within RTÉ News and Current Affairs.
