A class reunion is a meeting of former classmates, often organized at or near their former high school or college, by one or more class members. It is scheduled near an anniversary of their graduation, e.g. every 5 or 10 years. Their teachers and administrators may also be invited. Those attending will usually reminisce about their student days and bring one another up to date on what has happened since they last met.

Some class reunions also include a reunion class gift to the institution.

In film, television, and literature, class reunions have been a device used to show the eruption of emotions such as shame, hatred, and guilt within individual characters who, suddenly faced again with their own youth, become aware that they have been unable to cope with their past.

Those who used to be mistreated by their teachers or classmates believe they can now take revenge on their former torturers. Participants often nostalgically reminisce about their old school days or fondly remember their school pranks. They can be concerned about how their lives have turned out compared with the lives of their former classmates, and can feel pressured enough to fabricate stories about their careers, personal accomplishments, and relationships.

Another theme of this kind of fiction is former classmates taking up with their old flames again, either because they have developed into an admirable adult or for the opposite reason—because they have not changed at all.
