Johann Heinrich Roos (29 September 1631, Otterberg – 3 October 1685, Frankfurt) was a German Baroque era landscape painter and etcher.

[1] He trained with Guilliam du Gardijn,[2] Cornelis de Bie[1] and Barent Graat,[1] but the landscape painters Nicolaes Berchem and Karel Dujardin were more of an influence on him.

Between 1654 and 1659, Johann worked for Ernst, Landgrave of Hesse-Rheinfels (son of Maurice, lived 1623–1693), where he painted a portrait of A Prince (1654, Heidelberg, Kurpfälzisches Museum) and religious scenes.

[1] Due to unsatisfactory working conditions, he moved with his family to Frankfurt in 1667 and was very successful, but lost everything in a fire in 1685.

Among biblical, historical and genre scenes, Roos preferred subjects involving animals: the shepherds of the nativity, Venus and Adonis.
