York North is a provincial electoral district for the Legislative Assembly of New Brunswick, Canada. It was first created in the 1973 out of the old two member district of York by taking those parts of York County outside of the city of Fredericton and north of the Saint John River. The districts boundaries were significantly altered in 1994 — losing the villages of Nackawic, Millville and surrounding communities — and its name was changed to Mactaquac as a result.
