The Meramec River (), sometimes spelled Maramec River (the original US mapping spelled it Maramec but later changed it to Meramec), is one of the longest free-flowing waterways in the U.S. state of Missouri, draining 3,980 square miles (10,300 km2) while wandering 218 miles (351 km) from headwaters southeast of Salem to where it empties into the Mississippi River near St. Louis at Arnold and Oakville. The Meramec watershed covers six Missouri Ozark Highland counties—Dent, Phelps, Crawford, Franklin, Jefferson, and St. Louis—and portions of eight others—Maries, Gasconade, Iron, Washington, Reynolds, St. Francois, Ste. Genevieve, and Texas. Between its source and its mouth, it falls 1,025 feet (312 m). Year-round navigability begins above Maramec Spring, just south of St. James. The Meramec's size increases at the confluence of the Dry Fork, and its navigability continues until the river enters the Mississippi at Arnold, Missouri.

Merrimac, Illinois is a small unincorporated community in the historic Moredock Precinct of Monroe County, Illinois, United States. It is located in the American Bottoms, adjacent to the Mississippi River levee due south of that river's confluence with the Meramec.

Mastodon State Historic Site is a publicly owned, 431-acre (174 ha) archaeological and paleontological site with recreational features in Imperial, Missouri, maintained by the Missouri Department of Natural Resources, preserving the Kimmswick Bone Bed. Bones of mastodons and other now-extinct animals were first found here in the early 19th century. The area gained fame as one of the most extensive Pleistocene ice age deposits in the country and attracted scientific interest worldwide. The site was purchased by the state in 1976 following an effort to preserve it from destruction with the construction of Interstate 55. Archaeological history was made at the site in 1979 when scientists excavated a stone spear point made by hunters of the Clovis culture (14,000–10,000 years ago) in direct association with mastodon bones. This was the first solid evidence of the coexistence of people and these giant prehistoric beasts. The Kimmswick Bone Bed was added to the National Register of Historic Places in 1980.
