Oituz (formerly Grozești; Hungarian: Gorzafalva) is a commune in Bacău County, Western Moldavia, Romania. It is composed of six villages: Călcâi (Zöldlonka), Ferestrău-Oituz (Fűrészfalva), Hârja (Herzsa), Marginea, Oituz, and Poiana Sărată (Sósmező).

Oituz was the site of three battles during the First World War: the First, Second, and the Third Battle of Oituz.

According to Iorgu Iordan, the commune's name is of Turkic origin; otuz or oltuz means "thirty" in some Turkic languages.

Poiana Sărată village is part of Transylvania; in Austria-Hungary, it belonged to Háromszék County, and after a reorganization to Trei Scaune County in Romania until 1950.
