Preston is a provincial electoral district in the Halifax Regional Municipality in Nova Scotia, Canada.

It has existed from 1993 to 2013 and since 2021 and elects one member of the Nova Scotia House of Assembly.

The electoral district includes the majority African Nova Scotian communities of North Preston and East Preston, plus the communities of Cherry Brook, Lake Loon, Lake Echo, Mineville, Montague Gold Mines, Westphal, and part of the Tam O'Shanter Ridge neighbourhood of Dartmouth.

The electoral district was created in 1991 and was conceived to provide representation to the area's rural Black community.

The riding was re-created following the 2019 boundary review, mostly out of Preston-Dartmouth, but also out of parts of Waverley-Fall River-Beaver Bank, Cole Harbour-Portland Valley, Eastern Shore and a small part of Colchester-Musquodoboit Valley.
