Portrait of Sergey Aksakov is an oil painting completed by Ivan Kramskoi in 1878. The work presents a seated, elderly man identified as Sergey Aksakov, a notable Russian writer and public figure, rendered with careful attention to naturalistic detail. Painted during the later period of Kramskoi's career, the portrait reflects the artist's established reputation for psychological depth and realism in portraiture. The composition centers Aksakov in a three-quarter view, seated on a wooden bench against a dark, subdued background that brings focus to his face and hands.

The sitter is dressed in a grey overcoat with a red garment visible at the collar, and holds a walking stick in his lap. The artist uses a restrained palette, employing subtle gradations of light and shadow to model the features and textures, particularly in the rendering of Aksakov’s white beard and the folds of his clothing. The expression is contemplative, with the subject’s gaze directed slightly away from the viewer. This painting dates to 1878 and is part of a tradition of Russian realist portraiture in the late nineteenth century.

Ivan Kramskoi was a leading figure among the Peredvizhniki (Wanderers), a group of Russian realist artists who sought to depict the character and dignity of their subjects. The work is held in a Russian collection and is documented on tez-rus.net.
