Comănești (Romanian pronunciation: [koməˈneʃtʲ]; Hungarian: Kománfalva) is a town in Bacău County, Western Moldavia, Romania, with a population of 19,996 as of 2021.

[3] As of 2003, Comănești had an unemployment rate of 18.1%, much higher than the country's average, and the town was declared an underdeveloped region.

The town is in the center of a large coal field and there are also smaller amounts of oil in the area.

The Comănești Coal Mine, which in 1989 employed 5,000 people, was finally closed down in 2005, leaving the last group of miners (260 in all) unemployed.

The other major industry of the town is forestry, but the large lumberyard and factory were also closed; this area of enterprise is now dominated by small local businesses, but in the last few years some international investors started to appear in the city, especially in retail and commerce.
