Panjwayi is a district in Kandahar Province, Afghanistan. It is located about 35 kilometres (22 mi) west of Kandahar. The district borders Helmand Province to the southwest, Maywand District to the west, Zhari District to the north, Arghandab, Kandahar and Daman districts to the east and Reg District to the south. Panjwayi was reduced in size in 2004 when Zhari District was created out of the northern part of it, on the northern side of the Arghandab River, which now forms the northern boundary.
