August Allebé was an artist and teacher from the Northern Netherlands. His early paintings were in a romantic style, but in his later work he was an exponent of realism and impressionism. He was a major initiator and promoter of Amsterdam Impressionism, the artist's association St. Lucas, and the movement of the Amsterdamse Joffers. Amsterdam Impressionism – sometimes referred to by art historians as the School of Allebé – was the counterflow to the very strong Hague School in the movement of Dutch Impressionism. As a professor at the Royal Academy of Amsterdam he fostered a cosmopolitan attitude toward art and the promotion and motivation of his students, and provided a significant stimulus to developments in modern art.

Amsterdam Impressionism was an art movement in late 19th-century Holland. It is associated especially with George Hendrik Breitner and is also known as the School of Allebé.
