Theotokonymia (Gr. Θεοτοκονύμια) is the defining of various names and titles given to the Theotokos, of which there are over 6,000. Most of them have been received into the Orthodox Church through the revelation of a vision, such as the appearance of the Theotokos to a saint in the Orthodox church or through a variety of other reasons.

Though the term Theotokonymia is derived from the Virgin Mary's Greek name Theotokos, her surname's are derived from the various icons that exist and in iconography Panagia is the term used for any particular icon of the Theotokos.
