Sedgwick is a town in Hancock County, incorporated on January 14, 1789 from the township of Naskeag or T4, EPR.
First permanently settled in 1759 by Andrew Black, the town's modern name is in honor of Major Robert Sedgwick who captured three important trading posts from the French: Pentagoet (Castine) and Saint John and Port Royal, now in Canada.
The original name, Naskeag, derives from the Indian term for the end or the extremity. Naskeag Point, now in the adjoining town of Brooklin, extends into Blue Hill Bay.
The southern portion of Sedgwick fronts on Eggemoggin Reach and the broad lower portion of the Benjamin River.
