Ashot Msaker was an Armenian prince from the Bagratid family. He ruled during the years of waning influence of Arab rule in Armenia.

Upon his death in 826, Ashot bequeathed his land to two of his sons: the eldest, Bagarat Bagratuni received Taron and Sasun and inherited the prestigious title of ishkhanats ishkhan, or prince of princes, whereas his brother, Smbat the Confessor, became the sparapet of Sper and Tayk.
