Moncton South (French: '''Moncton-Sud''') is a provincial electoral district for the Legislative Assembly of New Brunswick, Canada. It occupies the southern portion of the city of Moncton.
It was created in 1973 out of the multi-member district of Moncton as Moncton West. It 1994, its boundaries were changed losing much of its northern part to Moncton Crescent while it also expanded to the east and, as a result, its name was changed to Moncton South. In 2006, it lost much of the territory it had gained to the east and was returned to its original name of Moncton West. In 2013 it expanded eastward again, taking in downtown Moncton, and was again renamed Moncton South.
On 17 April 2007, the MLA for the district at the time, Joan MacAlpine-Stiles crossed the floor from the Progressive Conservatives to sit as a Liberal, along with her husband, Wally Stiles, who was the MLA for Petitcodiac.[1]
