Island Lake State Recreation Area is a state-run park in Green Oak Township, Livingston County, in metro Detroit in Michigan.

The 4,000-acre (1,600 ha) park lies on the Huron River and Kent Lake, an impoundment of the river, just downstream of Kensington Metropark with which it is also connected by a bike trail.

It is the third busiest park operated by the Michigan Department of Natural Resources with visitation of 1.09 million in 2008.

The park has a group campsite and a canoe-in campsite, several miles of hiking and biking trails, a shooting range, swimming and a couple of small lakes.

It is the only Michigan park to have a hot air balloon launch area.
