Marbach am Neckar (pop. ca. 15.000) is a town on the river Neckar in Baden-Württemberg, Germany. The nearest larger cities are Ludwigsburg and Stuttgart (ca. 25 km).

Marbach is known as the birth place of the classical poet and dramatist, Friedrich Schiller. Although Schiller moved away as a child, he is commemorated in Marbach by the Schiller-Nationalmuseum und Deutsches Literaturarchiv (Schiller National Museum and German Literature Archive), one of the main archives of literature history in the country.

The town has a picturesque centre with several churches (the older one is from the 16th century) and many historical houses, including the house in which Schiller was born.

Marbach (Neckar) station is on the Backnang–Ludwigsburg railway and is currently the terminus of line S 4 of the Stuttgart S-Bahn, which is being extended to Backnang.
