Western pleasure is a western style competition at horse shows that evaluates horses on manners and suitability of the horse for a relaxed and slow but collected gait cadence, along with calm and responsive disposition. The horse is to appear to be a "pleasure" to ride, smooth-moving and very comfortable. Most light horse breeds in the United States and Canada may compete in western pleasure classes, either in open competition or at shows limited to a single breed. However, horse conformation and temperament play a role in this event, and hence animals of stock horse breeds that are calm, quiet, have collected, soft gaits and the strong muscling required to sustain slow, controlled movement are the most competitive.

Western riding is considered a style of horse riding which has evolved from the ranching and welfare traditions which were brought to the Americas by the Spanish Conquistadors, as well as both equipment and riding style which evolved to meet the working needs of the cowboy in the American West. At the time, American cowboys had to work long hours in the saddle and often over rough terrain, sometimes having to rope a cattle using a lariat, also known as a lasso. Because of the necessity to control the horse with one hand and use a lariat with the other, western horses were trained to neck rein, that is, to change direction with light pressure of a rein against the horse's neck. Horses were also trained to exercise a certain degree of independence in using their natural instincts to follow the movements of a cow, thus a riding style developed that emphasized a deep, secure seat, and training methods encouraged a horse to be responsive on very light rein contact.
