List of QI panellists

This is a list of the panellists that have appeared on the BBC television programme QI. The show premiered in September 2003, with Stephen Fry as its host. Fry continued hosting until March 2016, when "Series M" concluded and Sandi Toksvig took over. With very few exceptions, each episode features three guest panellists who alongside permanent panellist Alan Davies answer extremely obscure questions.
