Deizisau is located between the towns of Plochingen and Esslingen am Neckar, about 20 kilometers southeast of Stuttgart, the capital of Baden-Württemberg.

Deizisau is located on the left hillside of the Neckar-valley shortly after the "Neckarknie" in Plochingen where the river changes direction from northeast to northwest.

At the western border of Deizisau, the Körsch flows into the Neckar; in the east a part of the Plochinger Kopf above the river knee lies inside the boundary.

Adjoining municipalities are in the north Altbach, in the northeast Plochingen, in the southeast Wernau, in the south Köngen, in the southwest Denkendorf and in the northwest Esslingen am Neckar.When it was settled in the 8th century, the area belonged to the Lorsch Abbey an der Bergstraße.

The town itself belonged to the patrician family Bürgermeister from the free imperial city Esslingen since 1296 and did enter into the possession of the Esslinger Katharinenhospitals through purchase in the year 1411.

[9] At the beginning of the 17th century it raged at first the black death, killing 31 people in 1608, then the mercenary arms of the Thirty Years' War.

Only for a short time after the end of the Coalition Wars a worldwide climate disaster happened following the eruption of a volcano in Indonesia in 1816, the so-called Year Without a Summer.

In Deizisau it rained for 75 days in a row, hail destroyed the fields and the little harvest left could partly only be brought in after Christmas.

[13] On a rise in the Rotfeld between Deizisau and Köngen the famines are still reminded of through the hunger lime planted in the year 1833.

The World War II and thereby the era of Nazism ended in Deizisau on April 22, 1945, with the march-in of the American troops.

Thereafter, through the settlement of a lot of expellees, an additional Catholic community developed together with the neighboring village Altbach.

Moreover, Deizisau has a United Methodist church community, which has her Christ chapel in the Klingenstraße as house of prayer.

It is derived from the St. Katharinen-Spital in Esslingen, who not only possessed Deizisau for several centuries but additionally the villages Möhringen and Vaihingen a. d. Fildern taken over from the County Palatine of Tübingen.

Deizisau has a good Connection to the traffic system through the Bundesstraße 10, the proximity to the Bundesautobahn 8 and direct access to the Stuttgart S-Bahn in the neighbouring towns Altbach and Plochingen.
