Vakpatiraja I (reigned c. 917–944 CE), also known as Vappayaraja, 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. He appears to have made an attempt to throw off the Gurjara-Pratihara overlordship, and was the first Chahamana king to assume the title Maharaja.
