Rondu District (Urdu: ضلع روندو), also spelled Roundu District, is a district of Pakistan-administered Gilgit-Baltistan in the disputed Kashmir region. It is one of 14 districts of Gilgit-Baltistan. The district encompasses the entire Roundu Valley, which is the fourth-largest valley in Gilgit-Baltistan, after the Skardu, Khaplu, and Shigar valleys. The Roundu valley lies in the western part of the Baltistan Division and forms the main trade and travel route between the Baltistan Division and the Gilgit Division. The Rondu District was carved out of Skardu District in 2019.
