Eppingen (German: [ˈɛpɪŋən] ) is a town in the district of Heilbronn in Baden-Württemberg in southern Germany. The town has the second-largest population in the district.

Eppingen lies in the Kraichgau, a hilly region in southwestern Germany, close to the confluence of the Elsenz and Hilsbach Rivers.

Eppingen was first mentioned in 985 when Otto III gave the settlement to the diocese of Worms. The ending "-ingen" was common for towns colonised by the Alamanni clan in the 3rd and 4th centuries.

Eppingen was owned by Salier in the 11th century, and by the Staufer in the 12th century. In 1188, it became a fortified village and, in 1192, a town, elevated by Heinrich VI. The town was distrained several times in the 14th century, but never lost the status of a town. After the win of the Electorate of the Palatinate over margraviate Baden in 1435, it finally became a part of the Electorate of the Palatinate but was once more distrained to the knights of Gemmingen, from 1469 to approximately 1520. In the 15th and 16th centuries, Eppingen underwent an economic boom during which its Latin school was first mentioned (1421). In a time of the plague a part of the Heidelberg University moved to the Latin school in 1496.

During the Palatinate wars of succession, Eppingen functioned as the main storage facility for the German army. From 1695 to 1697, the Eppingen Lines (Eppinger Linien), a string of earthwork fortifications and watchtowers, were built. They served as large defending walls against French raids at that time. One watchtower, called the Chartaque, was built by local students to show the architecture of those ancient buildings. Eppingen was affiliated to Baden in 1803. It maintained the second oldest school of agriculture in Baden. At the end of the 19th century, Eppingen was connected to the railway network; the Kraichgau Railway was opened to Karlsruhe in 1879 and to Heilbronn in 1880 and the Steinsfurt–Eppingen railway, which connected to Heidelberg, was opened in 1899.

During 1971 and 1972, Eppingen annexed the six surrounding communities of Adelshofen, Elsenz, Richen, Rohrbach am Gießhübel, Kleingartach and Mühlbach. In 2000, Eppingen's population exceeded 20,000; and it attained the status of a district town in 2002.
