Firá (Greek: Φηρά, pronounced [fi'ra]) is the modern capital of the Greek Aegean island of Santorini (Thera). A traditional settlement, "Firá" derives its name from an alternative pronunciation of "Thíra", the ancient name of the island itself.

Fira is a city of whitewashed houses built on the edge of the 400 metres (1,312 feet) high caldera on the western edge of the semi-circular island of Thera. The two main museums of interest are the Archaeological Museum of Thera, 30 metres (98 feet) east of the cable car entrance, and the Museum of Prehistoric Thera at the southeast corner of the White Orthodox Cathedral of Ypapanti ([it]), built on the site of an earlier church destroyed in the 1956 Amorgos earthquake. The town also hosts a number of churches, including the Cathedral of Ypapanti and the Three Bells of Fira.
