Sandor is a census town falling within the Vasai (Bassein) municipality of the Palghar district, in the Konkan division of Maharashtra, India. Sandoris, the natives of Sandor, are predominantly Roman Catholic Kshatriyas of the Christian Bombay East Indian community, they converted in the colony centred around Bassein, the richest possession of the former Portuguese East Indies with the capital at Velha Goa, in the southern edge of the Konkan region. Prior to the arrival of Portuguese Armadas, there had also been some Nestorians descended from Jewish converts, by the efforts of the apostles Thomas or Bartholomew.

Roman Catholic Kshatriyas are a modern Christianised caste among Goan, Bombay East Indian, Mangalorean, Kudali & Karwari Catholics. They are patrilineal descendants of Kshatriya and Vaishya Vani converts to the Latin Church, in parts of the Konkan region that were under Portuguese Goan rule. They are known as Chardo in Goan Konkani, Charodi in Canarese Konkani & as Sandori or Vadval in Damanese and Mahraashtrian Konknni, while others also identify as Bhandari or Khatri in their Bombay East Indian dialects.
