stikman is a pseudonymous American street artist best known for placing images of humanoid, robot-like stick figures on the sidewalks of cities across the United States. He is reported to be Philadelphia native and has been active in street art since the 1960s, when he began his career at age 14 with anti-war graffiti.

The artist places the figures, most frequently on crosswalks, without any direct indication of authorship. This has led to articles in the media investigating the origin and authorship of the figures. While they are frequently interpreted as robot figures, the artist has said that they are simply "little men made of sticks".
