Baron Tennyson, of Aldworth in the County of Sussex and of Freshwater in the Isle of Wight, is a title in the Peerage of the United Kingdom.^[3] It was created in 1884 for the poet Alfred Tennyson. His son, the second Baron, served as Governor-General of Australia, and his grandson, the third Baron, as a captain for the English cricket team. On the death in 2006 of the latter's younger son, the fifth Baron, the line of the eldest son of the first Baron failed. The title was inherited by the late Baron's second cousin once removed, the sixth and present holder of the peerage. He is the great-grandson of Hon. Lionel Tennyson, second son of the first Baron.

Another member of the Tennyson family was the naval architect Sir Eustace Tennyson-d'Eyncourt, 1st Baronet. He was the grandson of Charles Tennyson-d'Eyncourt, uncle of the first Baron Tennyson.
