The Hamilton Harlequins are a New Zealand rugby union team.

Membership of the club is restricted to ek-Waikato (County) representatives, All Blacks or members of the New Zealand Services team, and certain invited players.

As a result, the New Zealand Barbarians was formed in Auckland and the Hamilton Harlequins in Waikato.

Many All Blacks have played in the New Zealand Harlequin's jersey over the years and, since the inclusion of the under 17 development programme in 1992, the club has given a clear development pathway for young up and coming Waikato rugby players.

A NZ Harlequin camp, backed by the NZ Rugby Foundation and supported by the Waikato Rugby Union for approx 40-45 players, is staged at St Paul's Collegiate School annually.
