William Russell Lane-Joynt (27 March 1855[1]– 6 June 1921),[2] born in Limerick, was an Irish barrister, philatelist and Olympic shooter.

[1][7] Lane-Joynt was Revolver Champion of Ireland four times[4] and won a silver medal for shooting at the 1908 Summer Olympics,[8] held in London, as a member of the Men's Running Target, Single Shot Great Britain team.

[10] Amongst Lane-Joynt's philatelic specialities were the line-engraved stamps of the British West Indies, Canada, Cape of Good Hope, Gold Coast, Great Britain, and the United States.

After the Duke's death, he became Honorary Curator of the collection that was bequeathed to the Dublin Museum of Science and Art.

[11] In 1921, he was invited to sign the Roll of Distinguished Philatelists[13] as one of the initial 25 candidates but was unable to do so due to ill health.
