Niagara Centre (renamed to Welland from 2006 to 2018) is a provincial electoral district in Ontario, Canada, represented from 1867 until 1977 and again since 2007 (under different boundaries) in the Legislative Assembly of Ontario.

In 2018, the name was changed back to Niagara Centre.

From 1967 to 1975, the southern part of the riding was covered by the Welland South district.

The pre-2018 Welland riding consisted of the cities of Welland, Thorold, Port Colborne, and the part of the City of St. Catharines lying south of a line drawn from the western city limit east along St. Paul Street West, northeast along St. Paul Crescent, east and south along Twelve Mile Creek, and east along Glendale Avenue to the eastern city limit.
