Charles Darwin is the title of two oil on canvas portraits by English painter John Collier.

He is depicted as a bald and white bearded old man, standing against a dark background, while looking directly at the viewer, dressed in a loose cloak and holding his hat in his left hand.

People who knew Darwin better were impressed with its resemblance and realism, and many of them believed that this was the best portrait ever made of him.

"[1] Darwin, in fact, stated that "Collier was the most considerate, kind and pleasant painter a sitter could desire.
