Duke Ellington (ডিউক এলিংটন) was an American pianist who was the greatest jazz composer and bandleader of his time. One of the originators of big-band jazz, Ellington led his band for more than half a century, composed thousands of scores, and created one of the most distinctive ensemble sounds in all of Western music.

At the end of the 1930s, Ellington began a nearly thirty-year collaboration with composer-arranger-pianist Billy Strayhorn, whom he called his writing and arranging companion.With Strayhorn, he composed multiple extended compositions, or suites, as well as many short pieces. For a few years at the beginning of Strayhorn's involvement, Ellington's orchestra featured bassist Jimmy Blanton and tenor saxophonist Ben Webster and reached what many claim to be a creative peak for the group. Some years later following a low-profile period, an appearance by Ellington and his orchestra at the Newport Jazz Festival in July 1956 led to a major revival and regular world tours. Ellington recorded for most American record companies of his era, performed in and scored several films, and composed a handful of stage musicals.

A major figure in the history of jazz music, Duke Ellington's career spanned more than half a century, during which time he composed thousands of songs for the stage, screen and contemporary songbook. He created one of the most distinctive ensemble sounds in Western music and continued to play what he called "American Music" until shortly before his death in 1974.
