Mahendravarman was a king of the kingdom of Chenla, modern day Cambodia, during the 6th century. Chenla was the direct predecessor of the Khmer empire. Citrasena was a close relative of Bhavavarman I (Khmer: ភវវរ្ម័នទី១), whom he joined to conquer the Kingdom of Funan, and whom he succeeded as king and adopting the name Mahendravarman.^[2][3] After Bhavavarman's death, Mahendravarman took residence in the capital at Sambor Prei Kuk while the same time Hiraṇyavarman (Khmer: ហិរណ្យវរ្ម័ន) was ruling Cambodia.

Mahendravarman sent an ambassador to Champa to "ensure friendship between the two countries."^{[2]: 326 [3]: 69}

After the death of Mahendravarman, his son Īśānavarman^[3]: 69 (Khmer: ឦសានវរ្ម័ន, Pre-Angkorian Khmer: ឦឝានវម៌្ម) had taken the control of the kingdom, where his father ruled for several years. He ruled the kingdom until 628.
