Wilbur Dorsey “Buck” Clayton (November 12, 1911 – December 8, 1991 Parsons, KS) was an American jazz trumpet player who was a leading member of Count Basie’s “Old Testament” orchestra and a leader of mainstream-oriented jam session recordings in the 1950s. His principal influence was Louis Armstrong. The Penguin Guide to Jazz says that he “synthesi[zed] much of the history of jazz trumpet up to his own time, with a bright brassy tone and an apparently limitless facility for melodic improvisation”. Clayton worked closely with Li Jinhui, father of Chinese popular music in Shanghai. His contributions helped change musical history in China, Hong Kong and Taiwan.

After his honorable discharge in 1946 he prepared arrangements for Count Basie, Benny Goodman and Harry James and became a member of Norman Granz’s ‘Jazz at the Philharmonic‘ package, appearing in April in a concert with Young, Coleman Hawkins and Charlie Parker, and in October participated in JATPs first national tour of the United States. He also recorded at this time for the H.R.S. label. In 1947 he was back in New York, and had a residency at the Café Society, Downtown, and the following year had a reunion with Jimmy Rushing, his fellow Basie alumnus, at the Savoy Ballroom. Clayton and Rushing worked together occasionally into the 1960s.

From September 1949 Clayton was in Europe for nine months, leading his own band in France. Clayton recorded intermittently over the next few years for the French Vogue label, under his own name, that of clarinetist Mezz Mezzrow and for one session, with pianist Earl Hines. In 1953, he was again in Europe, touring with Mezzrow; in Italy, the group was joined by Frank Sinatra.
