The Cretan derby (Greek: Το Κρητικό Ντέρμπι), also called Heraklion Derby (Greek: Ηρακλειώτικο ντέρμπι) or The Battle of Crete (Greek: Η Μάχη της Κρήτης) is an association football rivalry between Ergotelis and OFI, the two teams that have represented the city of Heraklion, Crete in the Greek Super League. Although the term "Cretan derby" has been used to describe almost every match-up between football clubs from Crete on any level of the Greek football league system, the OFI-Ergotelis rivalry is the most iconic, since it involves the two most prestigious clubs on the island and its roots can be traced back to the early days of Greek professional football.
