Absolutely.
Citizenship is in the eye of the beholder. Different countries have different rules. For example, you could be born in the USA (American citizen) of a French mother (French Citizen) and a German father (German citizen) You could have three different passports, But America would only view you as an American, Germany and/or France might recognize all three nationalities.
