The 40-acre Warren Wildlife Area lies in northeast Ohio, south-central Trumbull County, Weathersfield Township. It is located on Austintown Warren Road three miles south of the city of Warren. There is a small marsh located in the center of the area. The area consists primarily of bottomland hardwoods.

The area was acquired through a mitigation agreement. The area is now managed for public hunting and fishing.

There are many game animals found in the area including fox squirrel, wild turkey, white-tailed deer, and cottontail rabbits. Furbearers such as mink, skunk, opossum, and muskrat are also present. Many species of nesting and migrating birds also use this area at different times of the year. The marsh and river are also used by beaver, river otter, and migrating waterfowl with wood ducks being the dominant species.

There is one parking lot on the west side of the area off Austintown-Warren Road.
