Frederick Adolphus Philbrick, KC (13 June 1835 – 25 December 1910)[1][2] was an English barrister, judge, and an early philatelist.

He entered the Middle Temple in 1858 and was called to the bar in 1860, joining the Home Circuit.

He was appointed Recorder of Colchester in 1870, a Queen's Counsel in 1874, and was elected a bencher of the Middle Temple in 1876.

In 1866 he acquired the collection of Georges Herpin who coined the word "philatelie" in 1864.

Two pseudonyms used by Philbrick in his philatelic writing were, An Amateur and Damus Petimusque Vicissim (the motto of British Guiana).
