West Carleton-March Ward (Ward 5) is a city ward in Ottawa, Ontario, Canada.

Ward 5 was created for the 1994 Regional elections. At the time, it consisted of West Carleton Township, Goulbourn Township and Rideau Township. It was given the name Western Townships Ward in 1997. When Ottawa was amalgamated, the Ward was reduced to just West Carleton, and renamed West Carleton Ward. Its first election as West Carleton Ward was in 2000. In 2006, the boundaries were altered, and the ward was given its present name. Its southern border became Highway 7 and the Queensway and it lost some areas in the southeastern part of the ward. The ward also added the rural northern portion of the former city of Kanata. Its population in 2006 was 23,400 – the second least populated ward. Its area is 763 km², the largest city ward. It was represented by Eli El-Chantiry on Ottawa City Council from 2003 until 2022 when he retired. Clarke Kelly won the 2022 election to represent the ward.

Following the 2020 Ottawa Ward boundary review, the ward lost small sections of territory in the South March area and north of Stittsville to accommodate proposed housing developments.^[2]
