Hampton-Fundy-St. Martins is a provincial electoral district for the Legislative Assembly of New Brunswick, Canada. It was first contested in the 2014 general election as Hampton, having been created in the 2013 redistribution of electoral boundaries.

The district includes the Town of Hampton and a small part of the Town of Quispamsis, from which it runs southwesterly to Mispec, including parts of the City of Saint John south of the Mispec River and rural and suburban communities in between. It drew significant population from the former districts of Hampton-Kings, Saint John-Fundy, Saint John East and Quispamsis as well as a small part of Rothesay.

The riding was renamed Hampton-Fundy-St. Martins following the 2023 redistribution.

On May 11, 2024, John Herron was nominated as the Liberal candidate for the riding of Hampton-Fundy-St. Martins in the upcoming New Brunswick provincial election.
