The Alexander, later Hagart-Alexander Baronetcy, of Ballochmyle, in the parish of Mauchline, in the County of Ayr, is a title in the Baronetage of the United Kingdom. It was created on 22 January 1886 for Major-General Claud Alexander, who served in the Crimean War and represented Ayrshire South in Parliament as a Conservative. The third Baronet assumed the additional surname of Hagart. This was recognised by decree of the Lord Lyon in 1948.
The heir apparent to the baronetcy is the present holder's only son, Claud Miles (born 1998).
