Caledon is a town in the Regional Municipality of Peel in the Greater Toronto Area of Ontario, Canada. The name comes from a shortened form of Caledonia, the Roman name for what is now Scotland. Caledon is primarily rural with a number of hamlets and small villages, but also contains the larger community of Bolton in its southeastern quadrant, adjacent to York Region. Some spillover urbanization also occurs in the south bordering the City of Brampton.
