Ray McKinley (June 18, 1910 – May 7, 1995) was an American jazz drummer, singer, and bandleader. He played drums and later led the Major Glenn Miller Army Air Forces Orchestra in Europe. He also led the new Glenn Miller Orchestra in 1956.

Born in Fort Worth, Texas, United States, McKinley’s parents bought him his first drum set at the age of nine. Soon after he began playing with a local band called The Jolly Jazz Band in the Dallas–Fort Worth area. He left home when he was 15 and played with Milt Shaw’s Detroiters and the Smith Ballew and Duncan-Marin bands. His first substantial professional engagement came in 1934 with the Dorsey Brothers’ Orchestra. It was with the Smith Ballew band in 1929 that McKinley met Glenn Miller. The two formed a friendship that lasted from 1929 until Miller’s death in 1944. McKinley and Miller joined the Dorsey Brothers in 1934. Miller left for Ray Noble in December 1934, while McKinley remained.

The Dorsey brothers split in 1935, with McKinley remaining with Jimmy Dorsey until 1939, when he joined Will Bradley, becoming co-leader. McKinley’s biggest hit with Bradley, as a singer, was “Beat Me Daddy, Eight to the Bar“, which he recorded early in the year 1940 (and for which he got partial songwriting credit under his wife’s maiden name Eleanore Sheehy). McKinley is referred to as “Eight Beat Mack” in the lyrics to the song “Down the Road a Piece,” which he recorded as a trio with Will Bradley and Freddie Slack in 1940. This was the earliest recording of the song, which was written specifically for Bradley’s band by Don Raye.
