Founder of the Karorsinghia principality of the Sikhs, He belonged to the village of Barki in the district of Lahore. He had been forcibly converted to Islam during the time of Nawab Zakarya Khan. He, however, rejoined the Sikh faith receiving the rites of initiation at the hands of Diwan Darbara Singh. Karora Singh generally confined his activities to the tract lying south of the Kangra hills in Hoshiarpur district.

In 1759, after the death of Adina Beg Khan, Karora Singh killed Adina's diwan Bishambhar Mall, and seized considerable territory, including places such as Hoshiarpur, Hariana and Sham Chaurasi. Karora Singh was killed at Taraori, near Karnal, fighting against the Nawab of Kunjpura in 1761.
