The Church of Saint Catherine (Greek: Αγία Αικατερίνη) is a late Byzantine church in the northwestern corner of the old city of Thessaloniki Greece. The church dates to the Palaiologan period but its exact dating and original dedication are unknown. From its interior decoration which survives in fragments and is dated to ca. 1315 it has been suggested that it was the katholikon of the Monastery of Christ Almighty.
