The Battle of Panjwaii was fought in mid-2006 with primarily Canadian and Afghan soldiers, supported by small elements of Dutch, American, and British forces against the Taliban. There were two separate times in which the forces were involved in heavy fighting in the region. The first phase was fought in July 2006, and the second encounter lasted from September to October 2006.

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.
