Johan Barthold Jongkind (born June 3, 1819 - died February 9, 1891, was a Dutch painter and printmaker regarded as a forerunner of Impressionism who greatly influenced Claude Monet.

Jongkind was born in the town of Lattrop in the Overijssel province of the Netherlands near the border with Germany. Trained at the art academy in The Hague, in 1846 he moved to the Montmartre Quarter of Paris, France where he studied under Eugène Isabey and Francois-Edouard Picot . Two years later, his work was accepted at the Paris Salon and he received acclaim from critic Charles Baudelaire and later on from Emile Zola. However, an alcoholic who suffered from depression, Johan Jongkind's life proved to be a series of ups and downs.

In 1855, Johan Jongkind returned to live in Rotterdam and remained there until 1860. Back in Paris, in 1861 he rented a studio on the rue de Chevreuse in Montparnasse where some of his paintings begin to provide a glimpse of the Impressionist style to come. In 1862 he befriended the young Claude Monet who would later refer to Jongk as the "Master." The following year Jongkind exhibited at the first Salon des Refusés. Despite several successes, in another of his down periods the Impressionist group did not accept his work for their first exhibition in 1874.

In 1878 with his wife, the painter Joséphine Fesser , Johan Jongkind moved to live in the small town of La Côte-Saint-André near Grenoble in the Isère département in the southeast of France where he died in 1891. He is buried there in the local cemetery.
