"Robbie" is a science fiction short story by American writer Isaac Asimov. It was his first robot story and writing commenced on June 10, 1939. It was first published in the September 1940 issue Super Science Stories magazine as "Strange Playfellow", a title that was chosen by editor Frederik Pohl and described as "distasteful" by Asimov. A revised version of "Robbie" was reprinted under Asimov's original title in the collections I, Robot (1950), The Complete Robot (1982), and Robot Visions (1990). "Robbie" was the fourteenth story written by Asimov, and the ninth to be published. The story is also part of Asimov's Robot series, and was the first of Asimov's positronic robot stories to see publication.

The story centers on the technophobia that surrounds robots, and how it is misplaced. Almost all previously published science fiction stories featuring robots followed the theme 'robot turns against creator'; Asimov has consistently held the belief that the Frankenstein complex was a misplaced fear, and the majority of his works attempted to provide examples of the help that robots could provide humanity.

In 2016 Robbie won a retrospective 1941 Hugo Award for best short story.
