Meramec Caverns is the collective name for a 4.6-mile (7.4 km) cavern system in the Ozarks, near Stanton, Missouri. The caverns were formed from the erosion of large limestone deposits over millions of years. Pre-Columbian Native American artifacts have been found in the caverns. Currently the cavern system is a tourist attraction, with more than fifty billboards along Interstate 44 and is considered one of the primary attractions along former U.S. Highway 66. Meramec Caverns is the most-visited cave in Missouri with some 150,000 visitors annually. Meramec Caverns is ranked #178 on CaverBob.com's USA Long Cave list.

The Meramec Caverns have existed for the past 400 million years, slowly forming through deposits of limestone. In centuries past, Native Americans used the cavern system for shelter. The first cave west of the Mississippi River to be explored by Europeans, it was first visited in 1722 by a French miner.

During the 18th century, the cave was used for extracting saltpeter for the manufacture of gunpowder. In the Civil War era, the Union Army used the caves as a saltpeter plant, but the plant was discovered and destroyed by Confederate guerrillas, likely including the future infamous outlaw Jesse James. According to local legend, James and his brother and partner in crime Frank used the caves as a hideout in the 1870s. However, there is scant historical evidence to support this tradition. One legend in particular claims that a sheriff tracking the Jameses sat in front of the cave, waiting for Jesse and his gang to emerge; however, they had found another exit.

In 1933, the extended cave system was discovered, revealing the present 4.6 miles (7.4 km), and was introduced to the public as a tourist attraction in 1935 by Lester B. Dill, who invented the bumper sticker as a means of promoting the caverns.
