Shear Genius is an American reality television series on the Bravo network that focuses on hair styling. Contestants engage in weekly elimination competitions until a winner is determined. The show is hosted by Jaclyn Smith.

The first season of the show aired in April and May 2007, immediately after the low-rated Top Design wrapped up its run. Unlike its predecessor, however, Shear Genius became a word-of-mouth fan favorite and a second season started airing in June 2008. Despite the comparative success, Top Design was also renewed.

First season's judges included Smith, Sally Hershberger and Michael Carl along with a fourth guest judge each week. The second season judges are Kim Vo and Kelly Atterton. Rene Fris acts as the mentor to the stylists, in a similar role that Tim Gunn performs on Project Runway, but otherwise does not participate in judging.
