Ambrose A. Call State Park is a state park in Kossuth County, Iowa, United States, that commemorates the first European settler in Kossuth County. The park preserves rugged hills of old-growth forest on the East Fork of the Des Moines River.

Ambrose A. Call and his brother Asa staked their claim on the site of the future park on July 9, 1854. The next day Ambrose and traveling companion William Smith started building a log cabin while Asa went back to retrieve his family and more supplies. In 1925 Ambrose's daughter donated the site to the state of Iowa for a public park. While the original cabin is gone, a similar structure was moved from a nearby homestead and placed approximately where Ambrose's cabin stood.

Ambrose A. Call State Park boasts a log cabin-style lodge built in 1928 that can be rented for events. There is a campground with 16 sites, all but three with electrical hookups. Two miles (3.2 km) of trails wind through the forest and in winter there is a cross-country skiing trail.
