He is Professor Emeritus of History and Research Professor at the University of California, Los Angeles (UCLA) and Visiting Fellow at The Sir Arthur Lewis Institute of Social and Economic Studies (SALISES), University of the West Indies at Mona, Jamaica.

Hill is also literary executor of the estate of C. L. R. James and General Editor of The C.L.R. James Archives, Duke University Press.
Robert "Bobby" Hill was born in Kingston, Jamaica (his father Stephen O. D. Hill was a renowned impresario on the island), where he attended St George's College. His early interest in Marcus Garvey and his work was initiated by his late uncles, Frank Augustus Hill, a renowned journalist and labour activist, and Ken Hill, then Mayor of Kingston. Hill received further education at the University of London, the University of Toronto and the University of the West Indies, Mona, where he obtained a Master's degree in Political Science, his thesis focusing on "Marcus Garvey’s Political Activities in Jamaica between 1927 and 1935".
He subsequently held appointments at Dartmouth College, the Institute of the Black World in Atlanta, Georgia (Research Fellow, 1971), and in 1972 became Associate Professor in the Department of African-American Studies Northwestern University, Evanston, Illinois (1972–77).
