Kolar district (Kannada: ಕೋಲಾರ ಜಿಲ್ಲೆ About this sound pronunciation ) is a district in the state of Karnataka, India. Kolar is the district headquarters. Located in southern Karnataka, it is the state's easternmost district. The district is surrounded by the Bangalore Rural district on the west, Chikballapur district on the north, the Chittoor district of Andhra Pradesh on the east and the Krishnagiri and Vellore districts of Tamil Nadu on the south.

On 10 September 2007, it was bifurcated to form the new district of Chikballapur. Due to the discovery of the Kolar Gold Fields, the district has become known as the "Golden Land" of India.

Kolar, formerly known as Kolahala, Kuvalala and Kolala, was called Kolahalapura during the Middle Ages. In Kannada, kolahahapura means "violent city" and it was the battlefield for the warring Chalukyas in the north and the Cholas in the south. In 1004 AD, the Cholas annexed Kolar until 1116. Vishnuvardhana (1108-1142) freed Gangavadi from the Cholas and, to commemorate his victory, built the Chennakesava Temple at Belur.
