Sylhet District (Bengali: সিলেট জেলা), located in north-east Bangladesh, is one of the four districts in Sylhet Division, which contains Sylhet, the regional capital.
Administrative functions of Sylhet District commenced in 1772 when the East India Company appointed William Makepeace Thackeray as its first collector. And until 1878 it remained a part of Bengal Province under the Dhaka Division. However, in that year, Sylhet was moved to the newly created Assam Province, and it remained as part of Assam up to 1947 (except during the administrative reorganisation of Bengal Province between 1905 and 1912). Sylhet District was divided into five subdivisions and the current Sylhet District was known as the North Sylhet subdivision. In 1947, Sylhet became a part of East Pakistan as a result of a referendum (except 31⁄2 thanas of Karimganj subdivision) as part of Chittagong Division. It was subdivided into four districts in 1983–84 with the current Sylhet District being known as North Sylhet. It became a part of Sylhet Division after its formation in 1995. Sylhet has played a vital role in the Bangladeshi economy. Several of Bangladesh's finance ministers have been Members of Parliament from the city of Sylhet.

Sylhet District is divided into thirteen upazilas.
The upazilas are:

Sylhet has a typical Bangladeshi tropical monsoon climate (Köppen Am) bordering on a humid subtropical climate (Cwa) at higher elevations. The rainy season starts from April to October and it is so hot and humid with very heavy showers and thunderstorms almost every day, whilst the short dry season starts from November to February and it is very warm and fairly clear. Nearly 80% of the annual average rainfall of 4,200 millimetres (170 in) occurs between May and September.
The physiography of Sylhet consists mainly of hill soils, encompassing a few large depressions known locally as "beels" which can be mainly classified as oxbow lakes, caused by tectonic subsidence primarily during the earthquake of 1762.
Geologically, the region is complex, having diverse sacrificial geomorphology; high topography of Plio-Miocene age. Limestone deposits in different parts of the region suggest that the whole area was under the ocean in the Oligo-Miocene. In the last 150 years. three major earthquakes hit the city at a magnitude of at least 7.5 on the Richter Scale, the last one took place in 1918, although many people are unaware that Sylhet lies on an earthquake prone zone.
Shah Arefin Tila is a boulder-rich hill located in Companiganj Upazila of Sylhet District, Bangladesh. It forms part of Sylhet's renowned 'white stone' zone and has both touristic and geological value. Stone extraction at the hill was officially banned in 2016 due to environmental concerns. Later, in 2025, the Interim Government of Muhammad Yunus suspended leases of 17 quarries nationwide, including Shah Arefin Tila.
