Gustave Cariot (1872–1950) was a French Post-Impressionist and Divisionist painter known for his luminous landscapes that explore the effects of light, season and atmosphere. Largely self-taught, he grew up in Paris near the Place des Vosges before pursuing painting independently, working initially in the city and later in the surrounding countryside.

He began exhibiting at the Salon des Indépendants in the early twentieth century, where his structured compositions and refined handling of colour attracted attention. His series Le Poème des Saisons (1903), depicting the progression of the year, established his reputation. Cariot exhibited widely in Paris, including at the Salon d’Automne and with the Société des Artistes Indépendants, and was associated with the artist group La Société Moderne. His technique combines Divisionist principles with a more tactile surface, using small strokes and subtle impasto to build light and texture. Painting across France and along the Rhine, he remained focused on landscape as a subject of continuous change, exploring variations in time, weather and season. His work is characterised by a measured use of colour and a sustained engagement with natural light.
