Arnoraja (IAST: Arṇorāja, r. c. 1135–1150 CE) was an Indian king belonging to the Shakambhari Chahamana dynasty. He ruled the Sapadalaksha country, which included parts of present-day Rajasthan in north-western India. Arnoraja defeated the Ghaznavid king Bahram Shah in the Slaughter of Turushkas near Ajmer, and also defeated several neighbouring Hindu kings including the Paramaras and the Tomaras. He had to face defeats against the Chaulukyas, and was ultimately killed by his own son, Jagaddeva.
