Vishnuvardhana (r.1108–1152 CE) was a king of the Hoysala Empire in what is today the modern state of Karnataka, India. He ascended the Hoysala throne after the death of his elder brother Veera Ballala I in c.1108. Originally a follower of Jainism and known as Bitti Deva, he came under the influence of the Hindu philosopher Ramanujacharya, converted to Hindu Vaishnavism and took the name "Vishnuvardhana". Vishnuvardhana took the first steps in creating an independent Hoysala Empire in South India through a series of battles against his overlord, the Western Chalukya King Vikramaditya VI, and the Chola Empire to the south. He recovered parts of Gangavadi province (modern southern Karnataka) from the hegemony of the Cholas in the battle of Talakad, and parts of Nolambavdi. According to historian Coelho, the Hoysalas gained the dignity of a kingdom due to the efforts of Vishnuvardhana, whose rule was packed with "glorious" military campaigns. According to historians Sen, Chopra et al., and Sastri, Vishnuvardhana was a "great soldier" and an "ambitious monarch".
Hoysala literature in the Kannada language began to proliferate under the patronage of Vishnuvardhana. The mathematician Rajaditya wrote Vyavaharaganita and Lilavati on mathematics. According to the historian E.P. Rice, the epic poet Nagachandra was under Vishnuvardhana's patronage when he wrote the earliest extant Ramayana (a Jain version) in the Kannada language called Ramachandra charita purana, and an epic on the nineteenth Jain Tirthankar titled Mallinathapurana.
Vishnuvardhana is a 2011 Kannada comedy thriller film starring Sudeep, Bhavana Menon and Priyamani. The film was directed and written by P. Kumar, in his debut, and produced by actor Dwarakish.

The film was released on 8 December 2011. The film was officially remade in Bengali as Bachchan. The movie was reported to be inspired by the 2009 South Korean movie Handphone which the director had vehemently denied.
