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 October 13, 1926, in Pittsburgh, Pennsylvania, and took piano lessons from the age of eight. After noticing how many pianists attended his high school, he thought of taking up the trombone, but was unable to afford one. With a vacancy in the high school jazz orchestra, he took up the upright bass.
