Mount Stewart is a rural municipality in Prince Edward Island, Canada.

The community played an important role in the province's early transportation history, being the site of a bridge over the river along the route between the capital at Charlottetown and the shire town of Kings County at Georgetown.

In the early 1870s, the Prince Edward Island Railway ran its mainline between both communities through Mount Stewart.

If any one wanted to travel to Georgetown or Souris from Charlottetown, they would have to come through or make a stop at Mount Stewart.

The CNR constructed what was known as the "Short Line" between Mount Stewart and Lake Verde, permitting rail traffic to continue to serve the southeastern part of the province.
