Rebelo or Rebello is a Portuguese surname, also found in people with Portuguese ancestry or of Portuguese descent. This surname is mainly found in Portugal along with a very small distribution among Portuguese descendants in former Portuguese colonies like Brazil, India (Luso-Indians mainly in Goa), Angola, Mozambique and other places. In India, most people from the former Estado da Índia took the anglicised spelling of the surname- "Rebello", but many, especially those of Portuguese descent, kept the original spelling 'Rebelo'.
