Laughing Boy (painting)

Laughing Boy (Lachende jongen) is a circular oil-on-panel painting by the Dutch artist Frans Hals. It belongs to the tronie genre and was painted around 1625. It is in the collection of the Mauritshuis.

Another circular portrait with a laughing boy is in the collection of the Los Angeles County Museum of Art and shows a soap bubble on the right. A third version exists where the boy is grasping a whistle or flute. Several other circular portraits of laughing boys, all painted around the same period, with or without a bubble or a whistle, have been attributed to Hals in the past. Of the twenty or so paintings identified in 1974 by the Hals expert Seymour Slive, he considered only three to be authentic.
