Turnip Rock is a small geological formation in Michigan. It is a stack[1] located in Lake Huron, in shallow water a few meters offshore, near the rock called the Thumbnail which is the extreme tip of Pointe Aux Barques, a small peninsula in Pointe Aux Barques Township which in turn is the extreme tip of The Thumb, a large peninsula comprising several counties in eastern Michigan.[2][3][4]

Turnip Rock has been severely undercut by wave action,[5] so that its top has a significantly larger cross-section than its base. Its consequent unusual form, reminiscent of a turnip,[5][6] has made it a popular tourist attraction,[7] although it is located entirely on private land. Port Austin, the nearest large community, is the usual base for kayaking trips to Turnip Rock. A concrete collar has been built around the base of Turnip Rock at the waterline[8] to stop further undercutting.

Turnip Rock was one of twenty finalists in the 2013 "Seven Wonders of Michigan" contest sponsored by the Detroit Free Press and the Lansing State Journal,[9][10] but wasn't selected as one of the final seven.[11]
