Wilbur James "Jimmy" Cobb (January 20, 1929 – May 24, 2020) was an American jazz drummer. He was part of Miles Davis's First Great Sextet. He was awarded an NEA Jazz Masters Fellowship in 2009.

Cobb joined Miles Davis in 1958 as part of the latter's First Great Sextet, after Adderley recommended him to Davis. Cobb's best known recorded work is on Davis' Kind of Blue (1959). Cobb was the last surviving player from the sessions, a distinction that, after Davis's death in 1991, he held for almost three decades. He also played on other Davis albums, including Sketches of Spain (1960), Someday My Prince Will Come (1961), Miles Davis at Carnegie Hall (1962), In Person Friday and Saturday Nights at the Blackhawk, Complete, and briefly on Porgy and Bess (1959) and Sorcerer. His subtle and understated demeanor drew the admiration of many including Davis. However, this also meant that he did not get the same level of recognition that his fellow drummers would. Cobb had the propensity to eschew publicity and did not record his first set as bandleader until 1983, with the release of So Nobody Else Can Hear.

Cobb left the band in 1963, when Tony Williams was brought in by Davis. He formed a trio with pianist Wynton Kelly and bassist Paul Chambers, both of whom were part of Davis' rhythm section. The group toured and recorded as a trio, and also worked with Kenny Burrell, Wes Montgomery, Joe Henderson, J. J. Johnson and others. Chambers died in 1969, though Kelly and Cobb had occasionally used other bassists in the late 1960s as Chambers' health declined. Kelly died in 1971. Cobb went on to join the Great Jazz Trio, together with Hank Jones on piano and Eddie Gómez on bass. He also toured with Sarah Vaughan during the 1970s, and taught at Stanford University, University of North Carolina at Greensboro, and Berklee College of Music. He played in a tribute band called "4 Generations of Miles", together with Ron Carter (bass), Mike Stern (guitar), and George Coleman (tenor saxophone).

During his career, Cobb worked with Bill Evans, Clark Terry, Stan Getz, John Coltrane, Wes Montgomery, Art Pepper, Wayne Shorter, Benny Golson, Gil Evans, Kenny Dorham, Frank Strozier, Bobby Timmons, Booker Little, Johnny Griffin, Akiko Tsuruga, Bertha Hope, Hamiet Bluiett, Nat Adderley, Mark Murphy, Jon Hendricks, Joe Henderson, Fathead Newman, Geri Allen, Larry Willis, Walter Booker, Red Garland, Richie Cole, Ernie Royal, Jerome Richardson, Jimmy Cleveland, Philly Joe Jones, Sonny Stitt, Nancy Wilson, Ricky Ford, Richard Wyands, John Webber, and Peter Bernstein, among many others.
