The Infinite Monkey Cage is a BBC Radio 4 comedy and popular science series. Hosted by physicist Brian Cox and comedian Robin Ince, The Independent described it as a "witty and irreverent look at the world according to science". Since 2013 the show has been accompanied by a podcast, published immediately after the initial radio broadcast, which features extended versions of most episodes. The programme won a Gold Award in the Best Speech Programme category at the 2011 Sony Radio Awards, and it won the best Radio Talk Show at the 2015 Rose d'Or awards. The name is a reference to the infinite monkey theorem.

Brian Edward Cox is an English physicist and musician who is a professor of particle physics in the School of Physics and Astronomy at the University of Manchester and the Royal Society Professor for Public Engagement in Science.
