Karezat is in the north east of Pishin, Pakistan.

In Karezat, the largest city is Khanozai Bazar.

The name Karezat refers to the karezes, underground channels with vertical access shafts, used to transport water from an aquifer under a hill, in the villages of the tehsil.

It comprises many large villages which have large populations of the Kakar tribe; residents' livelihoods are based on agriculture.

In early times, farms were irrigated by the karezes, which were the major source of water in the area.
