Hochdorf is a municipality in the district of Esslingen, Baden-Württemberg, in southern Germany. The mayors are Roland Erhardt (1986 – 31 March 2009) and Gerhart Kuttler (since 1 April 2009).

Hochdorf is situated about 30 km southeast of Stuttgart in the northwestern foothills of the Swabian Jura and just south of the Schurwald. The municipality extends between Plochingen (west) and Kirchheim unter Teck (south) in the valley of the Talbach, shortly before it converges with the Fils.

Adjacent municipalities are Ebersbach (Göppingen district) in the east, Notzingen in the south, Wernau in the west, Plochingen in the northwest and Reichenbach an der Fils in the north (all Esslingen district).

Hochdorf consists of the village of Hochdorf, the Ziegelhof house, and the deserted village of Hinterburg.

Hochdorf was first mentioned in 1189 but probably originated in the 5th century. Until 1454, the place was owned by various monasteries, then it belonged to Württemberg. Within Württemberg, Hochdorf first belonged to Oberamt Kirchheim and, since 1485, to Oberamt Göppingen. In 1842, Kirchheim was reincorporated, where the city remained until the reorganization of the districts in 1938. Since then, Hochdorf has belonged to the district of Esslingen.

Since the Reformation, Hochdorf is predominantly Protestant coined.

Since the 1970s, there has been only one primary school in Hochdorf, the Breitwiesenschule. Secondary schools are attended in neighboring towns. Additionally, there are three kindergartens and a forest kindergarten in the municipality. The Kinderhaus am Talbach and the forest kindergarten "Die Waldmäuse" are operated by the Protestant Church. The "Albert-Schweitzer-Kinderhaus" is under the auspices of the Catholic Church. The Kinderhaus "Im Hof" is managed by the municipality of Hochdorf and exclusively offers full-day places. The children's and youth library has a collection of 4000 media.
