Jón Gnarr is an Icelandic actor, comedian, and politician who served as the Mayor of Reykjavík from 2010 to 2014. He was a well-known comedian and actor starting in the 1990s, including teaming with Sigurjón Kjartansson as the duo Tvíhöfði on radio and television. In 2009, he formed the Best Party, a political party that began as political satire but quickly turned into a real political player due to its electoral successes, which were perceived to be a reaction to the 2008–11 Icelandic financial crisis.
