New Maryland-Sunbury was a provincial electoral district for the Legislative Assembly of New Brunswick, Canada.

It was created in 1994 as a totally new district taking in large parts of York South and Sunbury as well as small pieces of several other districts.

In the 2006 redistribution of districts, it lost the community of Lincoln due to the rapid growth of both Lincoln and the village of New Maryland, both bedroom communities for Fredericton.

The district expanded eastward in 2013 to take in most of southern Sunbury County, including the Geary area.

* This was a new riding created largely out of the former ridings of York South and Sunbury, both of which were held by CoR prior to the election.
