Impressionism is a 19th-century art movement that originated with a group of Paris-based artists whose exhibitions brought them to prominence during the 1870s and 1880s. Impressionist painting characteristics include relatively small, thin, yet visible brush strokes, open composition, emphasis on accurate depiction of light in its changing qualities, ordinary subject matter, inclusion of movement as a crucial element of human perception and experience, and unusual visual angles.

The Impressionists faced harsh opposition from the conventional art community in France. The name of the style derives from the title of a Claude Monet work, Impression, soleil levant (Impression, Sunrise), which provoked the critic Louis Leroy to coin the term in a satiric review published in the Parisian newspaper Le Charivari.

The development of Impressionism in the visual arts was soon followed by analogous styles in other media that became known as impressionist music and impressionist literature.
