Colestin is an unincorporated community in Jackson County, Oregon, United States.

After selling his interest in the station in 1859, Byron Cole acquired land and a mineral spring further north.

[3] The change in the post office name was preceded by construction of a Southern Pacific (SP) railway station at this location.

In 1887, the SP had leased the Oregon and California Railroad line, which had extended as far south as Ashland by 1884.

[4] A railway timetable from that era lists Hornbrook as the next station south of Cole's on the SP's Mt.
