Fort Vasai (Vasai killa in Marathi, Fortaleza de São Sebastião de Baçaim in Portuguese, Fort Bassein in English) is a ruined fort of the town of Vasai (Bassein), Konkan Division, Maharashtra, India. The structure was formally christened as the Fort of St Sebastian in the Indo-Portuguese era. The fort is a monument of national importance and is protected by the Archaeological Survey of India.
