Arnold van Boonen (16 December 1669 – 2 October 1729) was a Dutch portrait painter.
He painted genre pictures in the style of the latter, representing subjects by candlelight, but met with such encouragement in portrait painting that he devoted himself almost wholly to that branch of art.
An excellent colourist, a faithful designer of his model, and highly skilled, he was soon distinguished as one of the ablest artists of his day.
He painted some large pictures for the halls of the different companies at Amsterdam and Dordrecht.
His son, Kasper van Boonen, also painted portraits, but in no way proved himself equal to his father.
