Cold Creek Conservation Area, usually referred simply as Cold Creek, is an ecologically diverse protected Area of Natural and Scientific Interest in south-central Ontario, Canada.

[2][3] It is located on the western end of King Township, overlapping the Oak Ridges Moraine.

The Government of Ontario Ministry of Natural Resources classifies the area as a provincially significant Area of Natural and Scientific Interest (Life Science) for its "provincially or regionally significant representative ecological features".

Cold Creek has hiking trails that cover the Oak Ridges Moraine and a boreal peat bog, among others.

[9] Nest boxes are distributed throughout the conservation area to house birds and bats.
