Throwback uniforms, throwback jerseys, retro kits or heritage guernseys are sports uniforms styled to resemble the uniforms that a team wore in the past. One-time or limited-time retro uniforms are sometimes produced to be worn by teams in games, on special occasions such as anniversaries of significant events.

Throwback uniforms have proven popular in all major pro and college sports in North America, not only with fans, but with the teams' merchandising departments. Because the "authentic" uniforms (accurate reproductions) and less-authentic "replicas" had been so popular at retail, the professional leagues institutionalized throwbacks as "third jerseys".
