Constantine III of Lampron was the Catholicos of the Armenian Apostolic Church between 1323 and 1326.
A short time after his election he traveled to Aleppo and there was invited to meet the Mamaluke sultan of Egypt Al-Nasir Muhammad. He was received with much honor and was able to persuade the sultan to make peace with Armenia. They signed a fifteen-year peace treaty, and Constantine returned to a rejoicing Sis.
