Sibi (Urdu and ; سيوي) is a district in the Balochistan province of Pakistan. The main mountain ranges are Zen, Bambore and Dungan. The climatic and topography of Sibi District is quite varied compared to other districts of Balochistan. It is also known as the "Hot spot" of Pakistan where the temperatures in the summer exceed 52.6 °C (126.7 °F). Until 2013 the district had two sub-divisions, Sibi and Lehri, further organized into Tehsils and sub-tehsils: Sibi, Lehri, Kutmandi and Sangan. Lehri was rejoined with Sibi district in 2018.

The early recorded history of Sibi District begins with the Hindu Sewa Dynasty. The Hindu Sewa dynasty ruled much of Baluchistan up until the 7th century AD. The Sibi division carved out of Quetta division still derives its name from Rani Sewi, the queen of the Hindu Sewa dynasty.

Until the end of the 15th century the district had been a dependency of Multan and had been part of Ghaznavid Empire ruled by petty chief named Nasiruddin Kubacha. Around 1500 it was taken by Shah Beg of the Arghun Dynasty from Samma Dynasty of Sindh and so came under the control of Kandahar. However, during the period of Mughal rule the territory was once again ruled from Multan. In 1714 the territory was conquered by the Kalhoras Amirs of Sindh, but they were then displaced by the Durranis. During the short rule of the Durranis, the local administrators were nominated from the Barozai Sub clan of the Panni( Panri) Tribe. In the 19th century it fell under Marris and Bugtis hand. To finish rebellion in the area as raised by Marri & Bugti Tribes, the British signed the treaty with Khan of Kalat in late 19th century were under the Sibi, Shalkot and Chagai territory leased out to British India.

The District of Sibi was established in 1903 during British Rule its area was larger than the current district and lay between 27°55' and 30°38'N and 67°17' and 69°50'E lying south of Loralai District, north of the Upper Sind Frontier District, west of Dera Ghazi Khan District and east of Kachhi, Bolan Pass and Quetta- Pishin. The total area of the district was 11281 sqmi, but this included Marri Bugti county (7,129 square miles) which not directly administered by the British, leaving 4152 sqmi that were directly administered by the British The population according to the 1901 census of India was 74,555 or 18 persons per square mile, the district contained four tehsils these were:

In 1974 the district was subdivided to create Naseerabad and Kohlu districts, in 1983 Dera Bugti District, and in 1986 Ziarat District. Until 2000, except for Naseerabad, these new districts were part of Sibi Division of Pakistan. In 2000 the third-tier "divisions" structure of government was dissolved. Two further new districts were cleaved out of its territory: Harnai in 2007 and Lehri in 2013. Lehri was reannexed into Sibi in 2018.
