Khairkot District (Pashto: خیرکوټ ولسوالۍ), also known as Katawaz (کټواز) or Zarghun Shar District (Pashto: زرغونښار ولسوالۍ, Dari: ولسوالی زرغونشهر), is a district of Paktika Province, Afghanistan. The district is within the heartland of the Sulaimankhel tribe of Ghilji Pashtuns.[1] The district capital is Khairkot town.
In 1998, the district had an estimated population of over 75,000.[2] However, by June 2004 the post-Taliban government separated off three new districts from the large Khairkot District. The new districts were Janikhel District, Yahyakhel District and Yusufkhel District.[3][4] The district population in 2004 of the reduced district was 38,024.[3]
