Johannes Hubertus Leonardus de Haas (25 March 1832 – 4 August 1908) was a Dutch animal and landscape painter, and a peripheral figure of the Hague School.

Born at Hedel, De Haas spend his youth in Amsterdam where he got his first art education at evening-classes at the Koninklijke Academie.

In 1855 he received good reviews for his pictures that were exhibited in Paris from the noted art critic Jean Baptiste Gustave Planche.

From 1860 his friend Gabriël also lived in Brussels, and De Haas often painted cattle in the landscapes of both Roelofs and Gabriel, fitting in perfectly with both their styles.

[4] In 1892 he was chosen by Queen Emma to make a selection from the paintings from the royal collection for an exhibition at the Alte Pinakothek in Munich.
