Herbert ('Bertie') Thomas Sullivan (13 May 1868 – 26 November 1928) was the nephew, heir and biographer of the British composer Arthur Sullivan. He grew up as his uncle's ward and worked briefly as an engineer. After his uncle's death, Sullivan became active in charitable work. He was co-author of a 1927 biography of Arthur Sullivan, well regarded in its day, but later discredited because of its suppression of the composer's diary entries that mentioned his gambling and philandering.
Sullivan inherited many of his uncle's papers and original music manuscripts. Sullivan left most of these to his wife, who died in 1957, and they finally were sold to collectors in 1966.
Herbert Sullivan was the third child and eldest son of Frederic and Charlotte Sullivan, one of eight siblings. When Fred Sullivan died aged 39 in 1877, his younger brother, the composer Arthur Sullivan, made himself responsible for the support of Fred's widow and eight children. In 1881, Charlotte married Captain Benjamin Hutchinson, a man 13 years her junior. Charlotte emigrated to the U.S. in 1883 with her husband and all her children except Herbert, who remained in England under the care of his uncle. At the age of nine, Sullivan began boarding school in Brighton, England. He studied in Germany in the autumn of 1884.
Arthur Sullivan’s health was precarious from the 1880s onwards, and when necessary Herbert accompanied his uncle to the South of France and other resorts where the composer rested. In late 1890, now 22 years of age, Herbert left his uncle's home for an engineering job connected with the laying of a cable between Haiti and Brazil. Though never formally adopted, Herbert was in many respects Arthur Sullivan's adopted son. When Arthur died in 1900, the German Emperor Wilhelm, an admirer of Sullivan’s works, sent Herbert a personal message of condolence. Herbert remained friendly with his uncle's collaborator, W. S. Gilbert, after his uncle's death; when he organised a Garrick Club dinner in 1908 in honour of Gilbert, the dramatist wrote, "My dear Sullivan, There is little need to tell you how deeply I appreciate the good feeling that actuated you in organizing yesterday’s most successful dinner. It is an instance of friendship that can never fade from my memory".
After his uncle's death, Herbert Sullivan inherited the bulk of the composer's estate, including his diaries and many of his important musical manuscripts. He became prominent in pro bono publico activities, and in April 1915 he contributed the manuscript of Utopia Limited by Gilbert and Sullivan to a charity auction in aid of the Red Cross. In 1923 he married Elena Margarita Vincent. He served as Warden of the Worshipful Company of Musicians in 1925 and as Master of the Company in 1926.
In 1927 Sullivan collaborated with Newman Flower on a biography of Arthur Sullivan. As Sullivan and Flower had exclusive access to the composer's diaries, the biography was regarded at the time as uniquely authoritative. Subsequently, when wider access to the diaries became possible, it was seen that Sullivan had suppressed mention of his uncle's gambling and womanising, and this evasion, combined with the lack of musical analysis in the biography, led to a lowering of its status among scholars.
Sullivan died suddenly in London in 1928, aged 60. His estate included many of his uncle's manuscripts. His widow remarried about 1929, becoming Mrs Elena M. Bashford. She died in 1957, and the manuscripts were sold at auction in 1966 by her estate, some going to museums and collectors in America and others remaining in England. Several of the autograph scores were bought by the Gilbert and Sullivan scholar and collector Dr Terence Rees and others by dealers.

- Charlotte died in January 1885, barely a year after the move to California. Hutchinson, unable to cope with this loss and his responsibilities, soon returned to England, leaving the six surviving children (Edith had died) to be raised mostly by their uncle William, with the financial support of their uncle Arthur.
