The Alexander, later Cable-Alexander Baronetcy, of the City of Dublin, is a title in the Baronetage of the United Kingdom. It was created on 11 December 1809 for William Alexander, Lord Mayor of Dublin. The second Baronet was a Director of the Bank of Ireland. The third Baronet was Attorney-General to Albert Edward, Prince of Wales, later Edward VII. The seventh Baronet assumed in 1931 by deed poll the additional surname of Cable. As of 31 December 2013 the present Baronet has not successfully proven his succession and is therefore not on the Official Roll of the Baronetage, with the baronetcy considered dormant.
This branch of the Irish Alexander family is descended from William Alexander, whose brother Nathaniel Alexander was the ancestor of the Earls of Caledon and the Earls Alexander of Tunis.
