Tadley Ewing Peake Dameron (February 21, 1917 – March 8, 1965) was an American jazz composer, arranger, and pianist.

Born in Cleveland, Ohio, Dameron was the most influential arranger of the bebop era, but also wrote charts for swing and hard bop players. The bands he arranged for included those of Count Basie, Artie Shaw, Jimmie Lunceford, Dizzy Gillespie, Billy Eckstine, and Sarah Vaughan. In 1940-41 he was the piano player and arranger for the Kansas City band Harlan Leonard and his Rockets. He and lyricist Carl Sigman wrote “If You Could See Me Now” for Sarah Vaughan and it became one of her first signature songs. According to the composer, his greatest influences were George Gershwin and Duke Ellington.

Dameron recorded a single notable project as a leader, The Magic Touch, but was sidelined by health problems; he had several heart attacks before dying of cancer in 1965, at the age of 48. He was buried at Ferncliff Cemetery in Hartsdale, New York.
