Equine agility or horse agility is a sport similar to dog agility but using horses. Horses are asked to navigate an obstacle course with guidance from a human handler on the ground. At lower levels, the horse may be guided with a lead rope but at higher levels the horse works without a lead and in some cases, without a halter.^[1] There also are competition levels where horses compete in the "wild" — outside of an enclosed arena, and competitions where horses are not judged live but rather via video sent in by their handlers.^[2] Any equine of any size may compete in agility, including miniature horses, donkeys, mules and draft horses.^[3]

In live competition, handlers are required to wear an equestrian helmet and cannot use whips or sticks. The horse is only allowed, at most, to wear a halter, lead rope and may wear leg protection such as splint boots. The lead rope must be loose and the handler cannot pull on it but must remain within a designated position with their horse.^[4] Competition usually consists of a course of eight or more obstacles. Examples of obstacles may include tunnels, jumps, a seesaw, passing through a curtain, weaving between poles or cones, passing through or over poles, branches, gates, hoops, water, or tarps; entering a trailer; rolling a ball, backing between two poles, stepping onto an object, standing still, carrying a light load, crossing a bridge, navigating a small maze or labyrinth, crossing over an A-frame, and so on.^[1] Courses are often timed, particularly at higher levels.
