Weinstadt (German pronunciation: [ˈvaɪnˌʃtat] ^ⓘ, lit. 'Wine City'; Swabian: Waistadt) is a town in the Rems-Murr district, in the state of Baden-Württemberg, Germany. It is located in the Rems Valley approximately 15 km east of Stuttgart. Its population in 2012 was 25,998.

The town is composed of five districts or Stadtteile which were formerly independent towns and villages. They are Beutelsbach, Endersbach, Großheppach, Strümpfelbach, and Schnait. The five towns were combined to form the city of Weinstadt in 1975. Today, the city is the 6th largest in Rems-Murr-Kreis.

As the name implies, Weinstadt is best known for its vineyards and production of wine. The Remstalkellerei (Rems Valley Winery), in the Beutelsbach neighborhood of Weinstadt, is a cooperative owned by the local growers and is the tenth-largest winery in Germany.

From 1958 through 1976, Stanford University in California, United States, maintained an "overseas campus" for Stanford undergraduates in Beutelsbach. The hilltop campus is now the Landgut Burg hotel and conference center.

The city limits of Weinstadt span the river Rems, which flows through the Rems Valley (Remstal) into the Neckar Basin. The Rems flows into the Neckar at Remseck am Neckar. The Stadtteil Großheppach lies to the north of the Rems, while the other Stadtteile lie to the south. At the southern part of the city, the vineyards climb the slopes at the edge of Schurwald. All Stadtteile have vineyards; that is the source for the name "Weinstadt."
