Nice Guy (also known as Nice Guy™ or the Nice Guy Syndrome) is a pejorative term referring to a social stereotype commonly associated with young adult males who view themselves as caring and emphatic gentlemen in courtship to increase their potential towards women.

Not to be confused with males who are nice in general, Nice Guys have been criticized on the internet by both males and females alike for being hypocrites or even misogynists potentially being driven by an ulterior motive, mainly in anticipation of a relationship or sexual favors in return, and are often mocked as the first citizens of the friend zone.

A masculine form of "people pleasing" first described by Dr. Robert Glover.
