Portrait of Winckelmann is an oil on canvas painting by the Swiss artist Angelica Kauffmann, from 1764.

It was produced in Rome and represents the famous archaeologist and art historian Johann Joachim Winckelmann, whose work greatly contributed to the revival of classical studies and the change in style from rococo to neoclassicism.

The gradient of green tones ranging from verdigris to olive on the background and on the clothing, complements the red fabric under the bas-relief.

Touches of white seem to light up the painting, as seen in the pages of the book, lace on the sleeves and collar, and support the construction lines of the painting (enhanced by light touches of yellow), one of which runs diagonally along the book and the table, and the other vertically at the face.

All the light in the painting comes from the left side, which is emphasized by the use of white and suggested by the touches of yellow.
