Frangokastello (Greek: Φραγκοκάστελλο) is the location of a castle and scattered settlement on the south coast of Crete, Greece, about 12 km (7.5 miles) east of Chora Sfakion and within the prefecture of Chania.

Frangokastello has an extensive, sheltered and gently shelving sandy beach, which has provided the basis for a low key tourist industry in recent years. Tourist accommodation is scattered over the flat plain around the castle, but the area's relative remoteness has discouraged major development.
