Masardis is a town in Aroostook County, incorporated on March 21, 1839 from the township T10 R5 WELS.
Thomas Goss of Danville (Auburn) arrived with his family in 1833 and became the first settler, creating a homestead on the west bank of the Aroostook River opposite the mouth of the St. Croix stream. Others followed during the 1830's.
In 1839 a fort or breastwork, with artillery was built where the St. Croix joined the Aroostook. During the Aroostook War, troops were stationed here. They made a brief foray above Fort Fairfield, then retreated back to Masardis with no casualties.
The town is just south of Ashland on Maine Route 11 with access to nearby Squa Pan Lake.
