Kavi Santokh Singh (8 October 1787 – 19 October 1843/1844) was a Sikh historian, poet and writer. He was such a prolific writer that the Sikh Reference Library at Darbar Sahib Amritsar was named after him, located within the Mahakavi Santokh Singh Hall. In addition to "Great Poet" (Mahākavī) Santokh Singh was also referred to as the Ferdowsi of Punjabi literature, Ferdowsi wrote ~50,000 verses while Santokh Singh's Suraj Prakash totals ~52,000. Other scholars have thought of Santokh Singh as akin to Vyasa. Gottlieb Wilhelm Leitner in 1883 wrote that, "Santokh Singh of Kantal in the Karnal District, has rendered his name immortal" through the production of his works.
