Painterliness is a concept based on German: malerisch ('painterly'), a word popularized by Swiss art historian Heinrich Wölfflin (1864–1945) to help focus, enrich and standardize the terms being used by art historians of his time to characterize works of art.

A painting is said to be painterly when there are visible brushstrokes in the final work – the result of applying paint in a manner that is not entirely controlled, generally without closely following carefully drawn lines. Any painting media – oils, acrylics, watercolors, gouache, etc. – can produce either linear or painterly work. Some artists whose work could be characterized as painterly are Pierre Bonnard, Francis Bacon, Vincent van Gogh, Rembrandt, Renoir, John Singer Sargent, and Andrew Wyeth (his early watercolors). The Impressionists, Fauvists and the Abstract Expressionists tended strongly to be painterly.

Painterly art often makes use of the many visual effects produced by paint on canvas, such as chromatic progression, warm and cool tones, complementary and contrasting colors, broken tones, broad brushstrokes, sketchiness, and impasto.
