Wertheim (East Franconian: Wärde) is a town in southwestern Germany, in the state of Baden-Württemberg with a population of around 23,400. It is located on the confluence of the rivers Tauber and Main. Wertheim is best known for its landmark castle and medieval town centre.

Wertheim is the most northerly town in the state of Baden-Württemberg. It is situated at the confluence of the rivers Tauber and Main, on the Main's left bank. It borders on the Odenwald hills and the Spessart range to the north across the river Main. Wertheim is located in the Main-Tauber district.

The following towns and communities border on Wertheim, listed clockwise starting in the east: Holzkirchen, Helmstadt and Neubrunn (all district Würzburg, Bavaria), Werbach and Külsheim (both Main-Tauber district), Neunkirchen (district Miltenberg, Bavaria), Freudenberg (Main-Tauber district), Stadtprozelten and Faulbach (both Miltenberg district) and Hasloch, Kreuzwertheim and Triefenstein (all Main-Spessart district, Bavaria).

Wertheim was founded between the 7th and 8th century. However, the first settlement was a town called Kreuzwertheim on the right bank of the river Main. From the early 12th century onwards, a branch of the noble family of the Reginbodons called themselves after the town. After the family of the Counts of Wertheim [de] had built a castle on the left bank of the river Main, a settlement developed at the foot of this dominating structure that was called Wertheim. It was mentioned for the first time in 779. In 1192, it was referred to as Suburbium castri Wertheim and in 1200 the town was referred to as an oppidum and in 1244 as a civitas.

Count Eberhard of Wertheim reigned from the year 1355 to 1373. In 1363 Emperor Charles IV granted him by degree the right to mint coins. The last Count of Wertheim was Michael III. He married Katharina, the oldest daughter of Ludwig of Stolberg. Michael died without producing a male heir and consequently the county passed to Ludwig of Stolberg. In 1574, after the death of Ludwig, the county passed on to his son-in-law Count Ludwig of Löwenstein.

The town developed into the center of the County of Wertheim. The county was governed by the House of Löwenstein-Wertheim. In 1630, the house split into two lines: the older Protestant line Löwenstein-Wertheim-Virneburg and the Catholic line Löwenstein-Wertheim-Rochefort. The county existed until 1806 when it was divided as a consequence of the German mediatization (Reichsdeputationshauptschluss). The area left of the Main river was given to the Grand Duchy of Baden, while the territories right of the Main were given to the Kingdom of Bavaria.

Established in 1406, the cemetery of the former Jewish community is one of the oldest in Germany. In use up until the 20th century, it is the oldest existing Jewish cemetery in Baden-Württemberg.

For many years Wertheim was home to Peden Barracks, a US Army installation. The US Army left Peden Barracks in the early 1990s as part of the post Cold War reorganization of US armed forces in Germany.

In 1938, Wertheim was merged with Tauberbischofsheim into the newly created district Landkreis Tauberbischofsheim. From 1972 onwards, 15 communities were incorporated with Wertheim. These 15 communities are: Bettingen, Dertingen, Dietenhan, Dörlesberg, Grünenwört, Höhefeld, Kembach, Lindelbach, Mondfeld, Nassig, Reicholzheim, Sachsenhausen, Sonderriet, Urphar and Waldenhausen. As of 1 January 1973 the Landkreis Tauberbischofsheim was merged into the new Main-Tauber-Kreis. Due to the incorporation of surrounding communities, Wertheim reached the 20,000 population mark in 1975. Wertheim became a Große Kreisstadt (district town) on 1 January 1976.

Burg Wertheim [de] (castle) is the landmark of the town. Wertheim has a medieval town center with half-timbered houses and small streets. The Gothic Stiftskirche was built in 1383 (today it is a Protestant parish church). Two clocks can be seen on the clock tower, one with an hour hand only, for the residents of the castle. The Kilianskapelle, a Gothic chapel, was constructed after 1469. The Engelsbrunnen ("Angels' well") from 1574 was built of the red sandstone typical of this area and derives its name from two little angels holding Wertheim's coat of arms.

Other sights include the Kittsteintor with flood markings from 1595 onwards and the Blaues Haus ("Blue house").

The outlying Stadtteil of Urphar features a medieval fortified church, Jakobskirche [de].

Located not far from Wertheim in the Tauber valley is Bronnbach Abbey, or Kloster Bronnbach [de], founded in 1150. The late-Romanesque and early-Gothic basilica was consecrated in 1222.
