Kabulistan (Pashto/Persian: ) is a historical regional name referring to the territory that is centered on present-day Kabul Province of Afghanistan. It included the land as far as Peshawar and Swabi in what is now Khyber Pakhtunkhwa, Pakistan.
In many Greek and Latin sources, particularly editions of Ptolemy's Geography, the name of the region is given as Cabolitae (). European writers in the 18th to the 20th centuries sometimes referred to Durrani Empire as the Kingdom of Caboul.
The earliest rulers of Kabulistan were the Kabul Shahis, who ruled the region between 565 and 879 AD. Kabul Shahis had built a defensive wall around the city of Kabul to protect it against invaders, but despite that, they were conquered by the Saffarids of Zaranj. The remains of these walls are still visible over the mountains which are located inside Kabul city.
