The British Nationality Act 1772 (13 Geo. 3. c. 21) was an Act of the Parliament of Great Britain. It was a British nationality law which made general provision allowing natural-born allegiance (citizenship) to be assumed if the father alone was British.
The act was one of the British Subjects Acts 1708 to 1772.
The whole act was repealed by section 28(1) of, and the third schedule to, the British Nationality and Status of Aliens Act 1914 (4 & 5 Geo. 5. c. 17).
