Cape Verdean nationality law is regulated by the , as amended; the Nationality Act, and its revisions; and various international agreements to which the country is a signatory. These laws determine who is, or is eligible to be, a national of Cape Verde. The legal means to acquire nationality, formal legal membership in a nation, differ from the domestic relationship of rights and obligations between a national and the nation, known as citizenship. Cape Verdean nationality is typically obtained under the principle of jus sanguinis, i.e. by birth in Cape Verde or abroad to parents with Cape Verdean nationality. It can be granted to persons with an affiliation to the country, or to a permanent resident who has lived in the country for a given period of time through naturalization.
