Adjud (Romanian pronunciation: [adˈʒud]; Hungarian: Egyedhalma) is a city in Vrancea County, Western Moldavia, Romania.

Adjud, situated north of the point where the river Trotuș enters the Siret, used to be a marketplace.

Geological research findings show the city's subsoil having layers of gravel and sand Levantine and Quaternary, forming significant hydrological aquifers deposits fed by the Trotuș and Siret rivers and direct rainfalls.

In the northern part of the town a settlement from the Bronze Age was discovered, which dates roughly from the second millennium BC and belongs to Monteoru culture.

The first mention of the town is made by its Hungarian name Egyedhalma ("in oppido nostro Egydhalm” meaning "in our city Gilles' Hill") in a Latin language document from 1433,[3] where Iliaș of Moldavia granted commercial privileges to Transylvanian Saxon merchants.

[4][5] The Battle of Adjud occurred here on 14 October 1788, during the Russo-Turkish War (1787–1792), pitting the armies of the Russian Empire and the Habsburg monarchy (under the command of field marshal Baron Spleny von Mihald) against those of the Ottoman Empire.
