Nepean is a federal electoral district in Ontario, Canada that was represented in the House of Commons of Canada from 1988 to 1997, and was reinstated during the 2012 electoral redistribution. The original riding was created in 1987 from parts of the Nepean—Carleton riding. It consisted of the City of Nepean. The electoral district was abolished in 1996 when it was redistributed between the Nepean—Carleton (54%) and the Ottawa West—Nepean (46%) ridings. The riding was then reinstated in 2012 by Elections Canada, taking effect upon the dropping of the writs for the 2015 federal election, scheduled for 19 October 2015. All of the current riding comes from parts of the former riding of Nepean—Carleton.
