The National Democratic Front for the Liberation of Oman and the Arabian Gulf (Arabic: الجبهة الوطنية الديمقراطية لتحرير عمان والخليج العربي, abbreviated NDFLOAG) was a guerrilla movement in the Arabian peninsula. In 1971, having suffered military setbacks, NDFLOAG began seeking cooperation with PFLOAG. In December 1971 NDFLOAG and PFLOAG merged, forming the Popular Front for the Liberation of Oman and the Arabian Gulf, although the two groups retained separate organizational structures.
