The 2009 Welsh Labour leadership election was held following the resignation of Rhodri Morgan, who stepped down after nine years as First Minister of Wales. Morgan had made clear his intent to resign in 2009 as far back as 2005. As Morgan had been elected unopposed in 2000, this was the first contested election for the Welsh Labour leadership for more than a decade.
The contest concluded on 1 December 2009 and was won on the first round by Carwyn Jones who won in all three sections of the ballot. As Welsh Labour was the senior partner in a Labour/Plaid Cymru coalition government, Jones was confirmed as First Minister the following week assumed office as First Minister on 10 December 2009. Both Edwina Hart and Huw Lewis served in Jones' governments until their retirement in 2016.
