Hamish & Andy are an Australian comedy duo formed in 2003 by Hamish Blake and Andy Lee. Best known for their various drive time radio programmes on the Hit Network, which aired in multiple formats until 2017, their shows gained consistently high market share and became the highest rated radio show in Australian history. Retiring after 14 years of broadcasting, the duo now produce a weekly self-titled podcast and occasionally publish a secondary programme, the Remembering Project, to revisit their old radio segments.

A double act is a form of comedy originating in the British music hall tradition, and American vaudeville, in which two comedians perform together as a single act, often highlighting differences in their characters' personalities. Pairings are typically long-term, in some cases for the artists' entire careers. Double acts perform on the stage, television and film.
