Frits Thaulow (20 October 1847 – 5 November 1906) was a Norwegian Impressionist painter, best known for his naturalistic depictions of landscape.

Thaulow, who had specialized in marine painting, turned to Skagen's favorite subjects, the fishermen and the boats on the shore.

His best paintings were made in small towns such as Montreuil-sur-Mer (1892–94), Dieppe and surrounding villages (1894–98), Quimperle in Brittany (1901) and Beaulieu-sur-Dordogne in the Corrèze département (1903).

[7] In Dieppe Thaulow and his wife Alexandra made themselves popular: they were friends with artist Charles Conder, and they met Aubrey Beardsley.

[8] Thaulow received a number of honors for his artistic activity, including his appointment as commander of the 2nd Royal Norwegian Order of St. Olav in 1905.
