In 2026, Rhode Island holds the title for the least number of state parks, with approximately 15 official state-designated parks. This is largely due to its status as the geographically smallest state in the U.S. However, it is important to distinguish between "state parks" and "protected areas." While Rhode Island has the fewest full-scale parks, states like Delaware and North Dakota also have relatively low counts (around 17 and 13-15 respectively). If you look at "National Parks," the answer changes: several states, including Delaware, Kansas, and Nebraska, have zero traditional "National Parks" (though they do have National Monuments or Historic Sites). For travelers, Rhode Island’s small number is actually a benefit; because the state is so compact, you can visit almost every single one of its coastal and woodland state parks in a single weekend, offering a variety of scenery from the cliffs of Newport to the forests of Glocester.
