Sir Arthur Aston (1590 – 11 September 1649) was an English professional soldier, most noted for his support for King Charles I in the English Civil War, and in folklore for the gruesome manner of his death in Ireland. He was from a prominent Roman Catholic family originating in Cheshire. He was killed during the Siege of Drogheda during the Cromwellian Conquest of Ireland. Early career in central Europe Aston was the son of another Sir Arthur Aston, of Fulham, Middlesex, and the grandson of Sir Thomas Aston of Aston in Bucklow Hundred, Cheshire. Aston's father was a professional soldier who had served in Russia in the 1610s, and, being a Catholic, had caught the attention and trust of the Polish king Sigismund III. Arthur Aston senior agreed to raise 2,000 British mercenaries for the Polish crown for the Turkish war of 1621.

He was captured by Swedish troops near Danzig in 1627.

Its strength had fallen so much, mostly due to sickness, that by 1634 Aston was recruiting Germans to fill the ranks.

There was uneasiness in many quarters about his religion, and he was forced to resign his command, although he received a knighthood for his services. In 1642, when the First English Civil War broke out, Charles initially refused to employ him on account of his Catholic faith, but Prince Rupert of the Rhine persuaded him to do so.
