Galaţi (Romanian pronunciation: [ɡaˈlat͡sʲ]) is a county (judeţ) of Romania, in Moldavia region, with the capital city at Galaţi.

Historically Galați is part of Moldavia. In 1858, it was represented by Alexandru Ioan Cuza at the ad hoc Divan at Iași, in the wake of the Crimean War. Prior to 1938 what is now eastern Galați was the separate county of Covurlui (Județul Covurlui). From 1938 to 1945 Galați was part of Ţinutul Dunării (Megacounty Dunării).

In 2002, it had a population of 619,556 and the population density was 139/km².

This county has a total area of 4,466 km².

The county lies on a low plain, between the Prut River in the East, the Siret River in the West and South-West. They both flow into the Danube which forms the border with Tulcea County in the South-East.

Due to the relief, the majority of the population in the rural areas work in agriculture. Fishing is another profitable occupation along the Danube and the Siret River. Galaţi is Romania's second harbour after Constanţa, the navigable channel on the Danube allowing the passage of large ships. In Galaţi there exist the biggest metallurgical complex in Romania – the Mittal-Sidex Complex. Also the second biggest shipyard can be found also at Galaţi allowing ships up to 55,000 tdw to be built.
