Frans Rijckhals, or François Ryckhals (3 May 1609, Middelburg - 29 July 1647, Middelburg) was a Dutch painter and designer. His works combine genre scenes with still-lifes.

He was probably a pupil of Pieter de Bloot. After working in his hometown, he went to Dordrecht from 1633 to 1634. He returned to Middelburg in 1638 and lived there until his death.^[1] In 1640, he and David Teniers the Younger worked together on a painting in Antwerp.^[2]

In 1642, he married the Burgomasters daughter and moved into their home, which is now a museum dedicated to him.^[2]

He was primarily known for his paintings of rural life, but also produced Italian-style landscapes and religious works. At the beginning of his career, he also painted animals.^[2] A large number of his works in Berlin, Saint Petersburg and Budapest were destroyed during World War II.^[1] Only twenty of his works are known to exist. These may seen at (among others) the Musée des Beaux-Arts de Dunkerque [fr], the National Museum, Warsaw and the Musée Fabre in Montpellier.

He was a follower of Willem Buytewech and Aelbert Cuyp and was influenced by Adriaen van de Venne. In turn, he influenced Philips Angel I.^[1] Some of his still-lifes were attributed to Frans Hals the Younger, due to a mistaken interpretation of his convoluted monogram. In fact, no works by Hals have been identified with any certainty.

Among his pupils were Laurens Bernards (c.1630-1676)^[1] and, possibly, Willem Kalf.^[2]
