2011 New Zealand Labour Party leadership election

The 2011 New Zealand Labour Party leadership election was held on 13 December 2011 to choose the thirteenth Leader of the New Zealand Labour Party. A Deputy Leader and a senior and a junior whip were also elected. Following the Labour Party's loss in the 2011 general election, leader Phil Goff and deputy leader Annette King resigned, prompting the leadership election, which was conducted as a secret ballot of the Labour caucus.

David Cunliffe, David Shearer and David Parker stood for the leadership, and Nanaia Mahuta and Grant Robertson contested the deputy position. Cunliffe and Mahuta ran as a ticket. During the campaign Parker pulled out of the race and endorsed Shearer. Shearer and Robertson won the votes for their respective positions. Chris Hipkins and Darien Fenton were chosen as the senior and junior whips, respectively.
