High School Reunion is a reality television series chronicling real-life high school reunions.

The program originally aired on The WB for two seasons between 2003 and 2005, and featured reunions of classes after ten years.

A new version of the series began airing on TV Land on March 5, 2008, focusing on the 20-year reunion of the 1987 graduating class of J.J. Pearce High School in Richardson, Texas. Filmed in Maui, the series featured documentary-style interviews with the classmates, who are assigned "labels" to describe their high school roles.

The series returned to TV Land in February 2009 with members of the Class of 1988 of Chandler High School in Chandler, Arizona reuniting and the promise that one of them would reveal a major secret. Once again class members had labels such as "The Class Clown", "The Cowboy", etc.

The series returned with its third season premiering on January 13, 2010. It follows the members of the Class of 1989 of Chaparral High School in Las Vegas, Nevada.
