Coldbrook Creek is an urban stream in Grand Rapids in Kent County, Michigan.

Its origin is the outflow of Fisk Lake on the John W. Blodgett Estate, and the stream eventually drains to the Grand River.

Although parts of the stream are now in underground culverts,[1] there are significant possibilities for daylighting, and open streambeds appear in areas on the campus of Aquinas College as well as within Highland Park.

Ke-way-coosh-cum, known in English as Long Nose, and a signer of the Treaty of Washington (1836), was killed by Was-o-ge-nan at the place where the creek enters the Grand River.
