The term copycat (also written as copy-cat or copy cat) refers to the tendency of humans to duplicate the behavior of others, as expressed in the saying, "monkey see, monkey do."

This notably happens in the case of "copycat crimes", where a notorious or unusual crime inspires a wave of similar activity; this can happen with crimes ranging from shoplifting of particular items and graffiti, up to copycat suicides and murders. The term is used both for the act and for the person. It is often used in the derogatory sense, meaning a plagiarist. The "copycat effect" refers to the tendency of sensational publicity about a violent murder or suicide to cause more of the same.

The expression may have originated from observing the habits of kittens that learned by imitating the behaviors of their mother. Copycat has been in recorded use since at least 1896, in Sarah Orne Jewett's "The Country of Pointed Firs" but the expression could be many decades older.
