Johann Philipp d'Arco, Count of Arco (11 May 1652 – 18 February 1704) was a soldier who served the Habsburg monarchy for 30 years.

A different general named Arco, Jean Baptist, Comte d'Arco was employed by the Electorate of Bavaria, Austria's enemy in the War of the Spanish Succession.

D'Arco was born in Arco, Trentino, and already had 30 years distinguished service when he was ordered by Louis William, Margrave of Baden-Baden in 1703 to defend Breisach to the last man against a French attack under Claude Louis Hector de Villars.

The "key" to southern Germany fell into enemy hands together with many supplies, guns and ammunition.

His second in command Luigi Ferdinando Marsigli was stripped of all honours and his sword was broken over him.
