Pieter Tjarck is a portrait painting by the Dutch Golden Age painter Frans Hals, painted in 1638 and now in the Los Angeles County Museum of Art, Los Angeles.

The painting shows a fashionably dressed gentleman leaning over the back of a chair holding a rose. This painting was documented by Ernst Wilhelm Moes in 1909 and Hofstede de Groot in 1910, who wrote:

PIETER TJARCK. M. 77. Half-length; in an oval of painted stone. A man seated, facing three-quarters right, looks at the spectator. His right arm rests on the arm of the chair; in the hand is a rose. He has a big moustache' and pointed beard. He is in black with a big broad hat and a soft close-fitting ruff. [Pendant to 232.] Canvas, 33 inches by 27 inches. See Moes, Iconographia Batava, No. 7993, i and 2. A copy is in the Liege Museum.
