The Alexander, later Cable-Alexander Baronetcy, of the City of Dublin, is a title in the Baronetage of the United Kingdom.

[2] It was created on 11 December 1809 for William Alexander, Lord Mayor of Dublin.

The seventh Baronet assumed in 1931 by deed poll the additional surname of Cable, being the surname of his mother, the Hon.

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.

The heir apparent is the present holder's son Fergus William Antony Cable-Alexander (born 1981).
