Wheelchair rugby (known as quad rugby in the United States) is a team sport for athletes with a disability. It is currently practiced in over twenty countries around the world and is a Paralympic sport.

Developed in Canada in 1977, the sport's original name was murderball. The United States name of quad rugby is based on the fact that all wheelchair rugby players need to have disabilities that include at least some loss of function in at least three limbs - most are medically classified as quadriplegic.

Wheelchair rugby is played indoors on a hardwood court. The rules include elements of wheelchair basketball, ice hockey, handball and rugby union. It is a contact sport and physical contact between wheelchairs is an integral part of the game. It has little in common with Rugby football except for the name.

The sport is governed by the International Wheelchair Rugby Federation (IWRF) which was established in 1993.

Wheelchair rugby's roots go back to wheelchair basketball and ice hockey. It was created in 1976 by Jerry Terwin, Duncan Campbell, Randy Dueck, Paul LeJeune and Chris Sargent, five Canadian wheelchair athletes in Winnipeg, Manitoba to be a sport for persons with quadriplegia.^{[citation needed]} At that time, wheelchair basketball was the most common team sport for wheelchair users. That sport's physical requirement for players to dribble and shoot baskets relegated quadriplegic athletes, with functional impairments to both their upper and lower limbs, to supporting roles. The new sport — originally called murderball due to its aggressive, full-contact nature — was designed to allow quadriplegic athletes with a wide range of functional ability levels to play integral offensive and defensive roles.
