Aubrey FitzClarence, 4th Earl of Munster (7 June 1862 – 1 January 1928) was an English aristocrat and a great-grandson of King William IV by his mistress Dorothea Jordan.

Aubrey's elder brother, Geoffrey FitzClarence, 3rd Earl of Munster, inherited the Munster earldom and the subsidiary titles of Viscount FitzClarence and Lord Tewkesbury when their father died in 1901.

[1] However, Geoffrey was serving in the British Army in South Africa at the time and he died nine months later without ever having returned to England.

[2] Aubrey had held the office of Gentleman Usher-in-Ordinary to Queen Victoria from 1885 to 1901 and to King Edward VII from 23 July 1901 until 7 February 1902, shortly after inheriting the earldom.

[4] Aubrey died unmarried at the age of 65, at which point his nephew, Geoffrey FitzClarence, became the 5th Earl of Munster.
