The Yukon New Democratic Party (NDP; French: Nouveau Parti démocratique du Yukon) is a social-democratic political party in the Yukon territory of Canada. The Yukon NDP first formed the government of the territory under the leadership of Tony Penikett from 1985 to 1992, and under the leadership of Piers McDonald from 1996 to 2000. The party's current leader is Elizabeth Hanson. The NDP sat as official opposition to the current Yukon Party government in the Yukon Legislative Assembly until May 2006. In the 2006 Yukon election later that year, the three incumbent New Democrat Members of the Legislative Assembly were reelected, but the party failed to win any additional seats and remained in third place behind the five members of the Yukon Liberal Party and the ten member Yukon Party majority
