The district's name is derived from the city Bilasuvar. "Bile" is derived from the Turkish word “bilya” which means lowland, while "suvar" means a "cavalryman".

The Persian historian Hamdullah Qazvini wrote that the medieval urban settlement of Bilasuvar was established by the emir of Buveyhi, Pilasuvar in the 10th century, and was hence named after him. In the 14th century, the city declined due to feudal civil strife. The name in Turkic means pure water falls, due to the area's numerous rivers, though given the largely flat terrain the reference to waterfalls is somewhat misleading. In 1930, Bilasuvar District was created with the centre in Pushkin Settlement. In 1938, the district was renamed Pushkin District. In 1963, the territory was united with Jalilabad District, and in 1964, it became an independent district again. After the collapse of the USSR in 1991, it returned to its historic name and was renamed Bilasuvar District.
