Progressive Conservative Association of Alberta

The Progressive Conservative Association of Alberta (often referred to colloquially as Progressive Conservative Party of Alberta) was a provincial centre-right party in the Canadian province of Alberta that existed from 1905 to 2020. The party formed the provincial government, without interruption, from 1971 until the party's defeat in the 2015 provincial election under premiers Peter Lougheed, Don Getty, Ralph Klein, Ed Stelmach, Alison Redford, Dave Hancock and Jim Prentice. At 44 years, this was the longest unbroken run in government at the provincial or federal level in Canadian history.

In July 2017, the party membership of the PC and the Wildrose Party voted to approve a merger to become the United Conservative Party (UCP). Due to previous legal restrictions that did not formally permit parties to merge or transfer their assets, the PC Party and Wildrose Party maintained a nominal existence and ran one candidate each in the 2019 election, in which the UCP won a majority, to prevent forfeiture of their assets. The UCP government, under Premier Jason Kenney, later passed legislation allowing parties to merge, clearing the way for the PCs to formally dissolve on February 7, 2020.
