This page lists baronetcies, whether extant, extinct, dormant (D), unproven (U), under review (R) or forfeit, in the baronetages of England, Nova Scotia, Great Britain, Ireland and the United Kingdom. The holders of some of the baronetcies listed on the lists have died but in each case, up to the present, no person has proved succession and thus been placed upon the Official Roll of the Baronetage. Those that are marked with a "D" in the last column are regarded as being dormant since, although heirs are known to exist, succession has not been proved within a period of five years from the death of the holder.
