Oberstammheim is a former municipality in the district of Andelfingen in the canton of Zürich in Switzerland.

In 2009, archaeologists announced the discovery of an Iron Age (late Hallstatt or early La Tène) tumulus burial, apparently of a Celtic nobleman. While there are comparable finds in Germany, the site is unique in Switzerland.^[3]

Oberstammheim is first mentioned in 761 as Stamhaim. In 1212 it was mentioned as in Stamehein superiori.^[4]

On 1 January 2019 the former municipalities of Oberstammheim, Unterstammheim and Waltalingen merged into the new municipality of Stammheim.

Oberstammheim has an area of 9.4 km² (3.6 sq mi). Of this area, 54.9% is used for agricultural purposes, while 36.7% is forested. Of the rest of the land, 8.2% is settled (buildings or roads) and the remainder (0.2%) is non-productive (rivers, glaciers or mountains).^[5]

The municipality is located in the Züricher Weinland on the border with the canton of Thurgau on the southern slope of the Stammerberg. It includes the village of Oberstammheim and the Zürich part of the hamlet of Wilen bei Neunforn. For a short time (1853–86) Wilen bei Neunforn, together with the Thurgau section of the hamlet, was an independent municipality.

Most of the population (as of 2000) speaks German (97.2%), with French being second most common ( 0.7%) and Italian being third ( 0.7%).

In the 2007 election the most popular party was the SVP which received 41.1% of the vote. The next three most popular parties were the FDP (16.2%), the SPS (14%) and the Green Party (10.9%).

The age distribution of the population (as of 2000) is children and teenagers (0–19 years old) make up 28.6% of the population, while adults (20–64 years old) make up 53.5% and seniors (over 64 years old) make up 18%. In Oberstammheim about 85% of the population (between age 25-64) have completed either non-mandatory upper secondary education or additional higher education (either university or a Fachhochschule).
