The Number Painter, also known as the Mad Painter, was a character on Sesame Street. He appeared in a total of ten skits which premiered on February 23, 1972, often repeated in episodes until 1988.

The Number Painter character was played by Paul Benedict, who went on to greater fame as Mr. Harry Bentley, the eccentric neighbor of George and Louise Jefferson on the 1970s CBS situation comedy The Jeffersons.

In all skits, although the painter is never shown actually moving his lips, he talks either towards the camera or to whomever he encounters (usually the two supporting roles noted below) via voiceovers using the actor's actual voice.

His outfit consists of a black-and-white striped shirt, gray pants held up with suspenders, black sneakers, and a paint-splattered smock, topped with a black bowler hat. He carries a can of paint and a brush, along with a model copy of the number he intends to paint so he can check his work.

The music for all the segments was written and performed by American composer Robert Dennis.
