Greenville is a town in Piscataquis County, Maine, United States. The town is centered around the lower end of Moosehead Lake, the largest body of fresh water in the state. Greenville is the historic gateway to the north country and a center for outdoor recreation in the area. Greenville High School, with 89 students, was ranked as the third best high school in Maine and one of the top 1,000 in the US in 2010. A small steamboat was launched in 1836 to tow logs, and in 1838 the first large lake steamer began operation. In later years, a succession of steamers by the name of Katahdin plied the waters. The current S/S Katahdin was built in 1914. In July 1884, the Bangor and Piscataquis Railroad (later, the Bangor and Aroostook Railroad) arrived at Greenville Junction. The Canadian Pacific Railway's subsidiary the International Railway of Maine was built through the village in 1888. Tourists were attracted by the region's scenic beauty, hunting and fishing. Consequently, several inns and hotels were built, including the Piscataquis Exchange Hotel, the Squaw Mountain Inn and the Moosehead Inn. Steamboat service was available across Moosehead Lake to the grand Mount Kineo House on a peninsula at Mount Kineo. Today, Greenville remains a popular resort area.
