Chimney Rock is a protected scientific and natural area in rural Dakota County, Minnesota.

The community and township of Castle Rock are eponymous with a similar formation which later collapsed.

Lone Rock in Empire Township was noted by Zebulon Pike in the early 1800s, but has since eroded significantly.

Chimney Rock was noted as a landmark for settlers who moved to Dakota County in the 1800s.

A local group of DNR volunteers, the Hastings Environmental Protectors, maintains the SNA.
