Walter Maynard Ferguson CM (May 4, 1928 – August 23, 2006) was a Canadian jazz trumpeter and bandleader. He came to prominence in Stan Kenton‘s orchestra before forming his own big band in 1957. He was noted for his bands, which often served as stepping stones for up-and-coming talent, his versatility on several instruments, and his ability to play in a high register.

Ferguson was born in Verdun (now part of Montreal), Quebec. Encouraged by his mother and father (both musicians), he started playing piano and violin at the age of four. At nine years old, he heard a cornet for the first time in his local church and asked his parents to buy one for him. When he was thirteen, he soloed with the Canadian Broadcasting Corporation Orchestra. He was heard frequently on the CBC, notably featured on a “Serenade for Trumpet in Jazz” written for him by Morris Davis. He won a scholarship to the Conservatoire de musique du Québec à Montréal where he studied from 1943 to 1948 with Bernard Baker.
