This is a list of living British royal family members who, through royal descent or marriage, currently hold the rank of Prince or Princess of the United Kingdom of Great Britain and Northern Ireland. There are 18 living princes and princesses by birthright, and a further 6 women who are princesses by marriage.
Women become princesses by marriage, but only use that title if their husband is the Prince of Wales (e.g. Catherine, Princess of Wales) or if they take their husband's full name (last done by Princess Michael of Kent in 1978).[2] Most women use a peerage derived from their husband, such as Duchess or Countess.[3] Men cannot become princes by marriage.[4]
