This is a list of Michigan state parks and related protected areas under the jurisdiction or owned by the Michigan Department of Natural Resources (DNR) Parks and Recreation Division. A total of 106 state parks, state recreation areas and trail state parks currently exist along with eight other sites as well as 16 state harbors on the Great Lakes. While the Parks and Recreation Division directly manages the large majority of the parks in the system, a few are either jointly-managed with other agencies or are leased to other governmental entities, either temporarily or on an ongoing basis. Michigan's 101 state parks and recreation areas cover with 14,100 campsites in 142 campgrounds and over of trails. The state parks and recreation areas statewide collectively saw more than 26 million visits in 2016. History Michigan's state parks system was started in 1919.

Because Mackinac Island State Park was a federal gift with its own commission and jurisdiction, for those reasons some choose to not consider it the first state park even though it predates Interlochen State Park by nearly 25 years. Since 1919, 33 additional state park units have been decommissioned for varied reasons. The majority of these former state park units, 16, were transferred to counties or cities and are still local parks today. Four of the former units were incorporated into Michigan's two National Lakeshores when were created in the 1960s and 70s, while five others were removed and reverted into surrounding state lands (state game areas, state forests, state fish hatcheries, etc.). Four of the units were incorporated into larger state recreation areas in the 1940s in the Greater Detroit area, although one of those recreation areas is now a local park. Two of the former state
