North Bogastow Brook is a stream that flows through the town of Holliston. It is a tributary of the Charles River and part of the Boston Harbor watershed. The brook originates from a wetland near the border of Holliston and Sherborn and flows southeast for about 5 miles before joining the Charles River near Medway. The brook passes through several ponds, including Lake Winthrop, which is a popular recreational area for Holliston residents.

Fisk Street has a bridge crossing Bogastow Brook. The parking lot for the Amerasport Sporting Goods store is adjacent to the creek and the bridge.
