Florya's name, according to the Byzantine scholar Michael Psellos, who found it cited in an imperial Chrysobull, comes from the Greek word "Phlorion". It derives possibly by a certain Florus, who lived in this neighborhood during the early Byzantine age.
One part of the neighborhood is also called Şenlikköy.
