Tovma Artsruni (Armenian: Թովմա Արծրունի; also known in English-language historiography as Thomas Artsruni) was a ninth- to tenth-century Armenian historian who authored the History of the House of Artsrunik (Patmut’iwn Tann Artsruneats’).

However, Tovma's most valuable contributions are found in the second and third volumes, which accurately detail Armenian life under the rule of the Arab Caliphates and in particular the 851 Arab military expedition led by the Turkic general Bugha al-Kabir, its subsequent consequences, and the establishment of the independent Bagratid kingdom of Armenia north of Lake Van.

[4] The precise date that Tovma completed his work is unknown, although some historians have determined that it was composed sometime after 905.

[5] Tovma's work ends with an incomplete 29th chapter, yet several unknown authors (collectively called Ananun 'anonymous' in Armenian historiography) took it upon themselves to continue Tovma's History down to the 1370s and added an appendix and colophon.

[1] Tovma's History was first published in 1852 in Constantinople in Armenian and was subsequently translated into French by Marie-Félicité Brosset in 1862.
