Simeon I of Yerevan or Simeon Yerevantsi was the Catholicos of All Armenians from 1763 to 1780. In 1771, he founded a printing press at the Etchmiadzin Cathedral, the first in Armenia. According to Rouben Paul Adalian, the pontificate of Simeon I of Yerevan marked the reemergence of Etchmiadzin as a "truly important center of Armenian national affairs".
