Arthur Tempest Blakiston Dunn (12 August 1860 – 20 February 1902) was a noted amateur footballer who founded the English boarding school Ludgrove in 1892.

Alcock described Dunn, who usually played inside-left as "A good centreforward, rather light, but has plenty of pluck, and is a sure shot at goal", and "has great pace, and both dribbles and middles well".

During the latter game he went off with a knee injury early in the second half, an incident that many believed cost his side the cup, as with no substitutes allowed in those days the Old Etonians had to play on with ten men.

His third cap came on 5 March 1892 in a 2–0 victory over Wales at Wrexham, whilst his final international appearance was to end in a 4–1 win over Scotland at Ibrox Park, Glasgow, on 2 April the same year.

[1] In the week preceding his death, he had refereed a football match between Ludgrove's own XI and Oxford University and played hockey on the ice at Trent Park near the school, when he complained of tiredness.

His only son, John H. M. Dunn, became a 2nd Lieutenant with the Royal Field Artillery and was killed in action in the First World War on the Somme in September 1916.
