Veera Ballala II (Kannada: ವೀರ ಬಲ್ಲಾಳ 2) (r. 1173–1220 CE) was the most notable monarch of the Hoysala Empire. His successes against the Yadavas of Devagiri, the Southern Kalachuris, the Pandyas of Madurai and the waning Western Chalukya Empire, and his domination over the diminishing Cholas of Tanjore took the Hoysalas to their peak of power. The historian Chaurasia claims by the end of the 12th century, Ballala II's conquests had made the Hoysalas the most powerful dynasty of the Deccan. According to historian Derrett, Ballala II was "the most outstanding among Hoysala kings", and historian William Coelho in comparing Ballala II to King Vishnuvardhana writes, "he vied in glory with his grandfather".
