Schwaigern (German: [ˈʃvaɪɡɐn] ) is a town in the district of Heilbronn, Baden-Württemberg, Germany. It is situated 12 km west of Heilbronn.

The neighbouring towns and municipalities of Schwaigern (clockwise) are: Leingarten, Nordheim (Württemberg), Brackenheim, Eppingen, Gemmingen and Massenbachhausen (all in the district of Heilbronn).

Schwaigern consists of Schwaigern itself and its districts Massenbach, Stetten am Heuchelberg and Niederhofen. Schwaigern has approximately 11,000 inhabitants.

Finds of the Neolithic era and during the Roman period show an early settlement of this area. The town was first mentioned in writing in the Lorsch codex of 766. Bertilo, Lord of Schwaigern, is first mentioned in 1120. The construction of a church is proved in the 13th century. Bertilo's descendants took on the name "Lords of Neipperg" in 1241, after their castle of Neipperg near Brackenheim. In 1407 they also acquired the Lordship of Klingenberg near Heilbronn. In 1702, Schwaigern became the residence of the Lords of Neipperg, who were elevated to the rank of counts in 1726. In 1766, the County of Neipperg became an Imperial State of the Holy Roman Empire, mediatised to the Kingdom of Württemberg in 1806. The last ruling count, Adam Albert von Neipperg, married Napoleon's widow Marie Louise.

The village received the right to hold a market in 1486. After 1630 the Black Death killed a large proportion of the inhabitants. In 1690, during the War of the Grand Alliance, the then Schwaigern Castle was burned down. In 1806, the town came to Württemberg by mediatization and Reichsdeputationshauptschluss. The castle was rebuilt until 1839 and is still today owned by the comital family of Neipperg. Several fires destroyed large areas of the medieval town centre in the 19th and 20th centuries. In 1971/1972 Massenbach, Stetten am Heuchelberg and Niederhofen were incorporated.

The Lords of Neipperg became Protestants around 1530. Therefore, each of Schwaigern, Stetten am Heuchelberg and Niederhofen is a Protestant parish. Massenbach and Massenbachhausen have a common Protestant parish. In 1717, Wilhelm Reinhard von Neipperg, the first count and an Imperial field marshal in the Habsburg service, returned to the Catholic Church. The Catholic parish St. Martinus Schwaigern is responsible for Schwaigern, Stetten, Niederhofen and Neipperg (part of Brackenheim). The Catholic parish St. Kilian Massenbachhausen is responsible for Massenbachhausen and Massenbach. Also the New Apostolic Church has a parish in Schwaigern.

The Young People's Society of Christian Endeavour has local groups in Schwaigern, Stetten and Niederhofen. In Massenbach there is a local group of the YMCA.
