There have been four baronetcies created for members of the Harmsworth family, all in the Baronetage of the United Kingdom.
The Harmsworth baronetcy, of Elmwood, in the parish of St Peter's, Thanet, in the County of Kent, was created in the Baronetage of the United Kingdom on 23 August 1904 for the press lord Alfred Harmsworth.
[1][2] He was later created Viscount Northcliffe, with which title the baronetcy merged and became extinct on his death in 1922.
The title became extinct in 1980 on the death of his younger son, Arthur Geoffrey Annesley Harmsworth, the third Baronet.
The heir apparent is the present holder's son, Hildebrand Esmond Miles Harmsworth (born 1964).
