Jean Hans Egger was an Austrian painter.

Hans Egger studied between 1918 and 1922 at the Munich Art Academy under Heinrich von Zügel and Carl Johann Becker-Gundahl, with Becker-Gundahl in particular exerting a great influence on him. He then went on study trips to Italy, Holland and Scandinavia, where he got to know the artist couple Oda and Christian Krohg and Edvard Munch, among others.

In autumn of 1924 Egger went to France and changed his name to Jean Egger. In Paris he made the acquaintance of prominent members in the art and cultural scene, including Chaim Soutine, Moise Kisling, Leopold Zborowski, Beatrice Hastings and Paul Clemenceau, the brother of the French President. Together with Signe Wallin, his partner, Jean Egger traveled to Sweden in the summer of 1930 and painted a series of landscapes, which he successfully exhibited in the Paris autumn exhibition.

Two years later, his lung disease forced him to move to Pollença on the Spanish island of Mallorca. On October 16, 1934, Jean Egger died of complications from tuberculous meningitis and was buried in his hometown.
