Griesheim (German pronunciation: [ˈɡʁiːsˌhaɪ̯m] ^ⓘ) is the largest town in the Darmstadt-Dieburg district of Darmstadt in the southern state of Hesse. It has just over 28,000 inhabitants as of December 2023.^[3]

Griesheim is known for being the location of the first German airfield, which was founded in 1908. More recently, in 2013, news of the Dagger Complex—which emerged as the most important of the NSA's headquarters in Europe in the wake of the global surveillance disclosures—brought Griesheim worldwide attention.

The town of Griesheim is also known in the region as "Onion City," a reference to the statue of the "Zwiebelfrau" ("Onion Woman") in the market square.
