American naive art refers to a style of painting created by artists who lack formal training. These artists often use simple forms, bright colors, and childlike perspectives to express their ideas. The artwork typically reflects personal experiences, cultural themes, and everyday life, making it relatable and accessible to a wide audience. This genre gained popularity in the 20th century, with notable artists like Henry Darger and Grandma Moses emerging as key figures. Their works often feature whimsical scenes, rural landscapes, and folk themes, showcasing a unique vision that contrasts with traditional art movements.
