Willimantic is a town in Piscataquis County, incorporated as the town of Howard on February 22, 1881 from Howard Plantation. Two years later the name was changed to Willimantic, for the Connecticut town of that name.
The Willimantic Thread Company of Connecticut bought land here in 1879 and in 1886 established a mill to create spools. In 1912 the mill was moved to Milo.
Located on the western end of Sebec Lake, the town offers many camping and fishing opportunities. Maine Route 150 runs north from Guilford and terminates at the village of Sebec Lake, not to be confused with the town of Sebec at the far eastern end of the Lake.
