Poland Spring is a brand of bottled water, produced in Poland, Maine. It is named after the original natural spring in the town of Poland, Maine it was drawn from. Today it is a subsidiary of BlueTriton Brands, formerly Nestlé Waters North America, and sold in the United States. The spring was first exploited commercially in 1859 by Hiram W. Ricker, owner of a nearby inn. Contemporary demand is so great the brand's water is derived from multiple sources in the state of Maine including Poland Spring and Garden Spring in Poland, Maine, Clear Spring in Hollis, Evergreen Spring in Fryeburg, Spruce Spring in Pierce Pond Township, White Cedar Spring in Dallas Plantation, and Bradbury Spring in Kingfield, and Cold Springs in Denmark.

Poland Spring was the top-selling spring water brand in America in 2006. In 2007, the Poland Spring brand adopted a bottle using 30% less plastic, as did the other Nestlé Waters North America brands.
