The 28th Alberta Legislative Assembly was in session from May 23, 2012, to April 7, 2015, with the membership of the assembly determined by the results of the 2012 Alberta general election held on April 23, 2012. The Legislature officially resumed on May 23, 2012, and continued until the third session was prorogued and dissolved on April 7, 2015, prior to the 2015 Alberta general election on May 5, 2015.
Alberta's twenty-sixth government was controlled by the majority Progressive Conservative Association of Alberta, led by Premier Alison Redford until her resignation on March 23, 2014, and subsequently led by Dave Hancock temporarily until Jim Prentice was confirmed leader of the Progressive Conservatives in September. The Official Opposition was led by Danielle Smith of the Wildrose Party until she crossed the floor to join the PCs, and the opposition was subsequently led by Heather Forsyth. The Speaker was Gene Zwozdesky.
