The First Barr Ministry was the 13th ministry of the Government of the Australian Capital Territory, and was led by Labor Chief Minister Andrew Barr and his deputy Yvette Berry. It was appointed on 15 December 2014 following the resignation of Katy Gallagher as Chief Minister and the subsequent election of Andrew Barr as her replacement by the Australian Capital Territory Legislative Assembly. Green's Shane Rattenbury continued to serve as a minister for the remainder of the parliamentary term, as part of the Labor-Greens parliamentary agreement signed in 2012 at the start of the term.
