Raymond Matthews Brown (October 13, 1926 – July 2, 2002) was an American jazz double bassist, known for his extensive work with Oscar Peterson and Ella Fitzgerald. He was also a founding member of the group that would later develop into the Modern Jazz Quartet.

Ray Brown was born on October 13, 1926, in Pittsburgh, Pennsylvania, and took piano lessons as a child. After noticing how many pianists attended his high school, he thought of taking up the trombone, but his father was unable to afford one. With a vacancy in the high school jazz orchestra, he took up the upright bass instead.
