Robert Edward Duncan was an American poet and a devotee of Hilda "H.D." Doolittle and the Western esoteric tradition who spent most of his career in and around San Francisco. Though associated with any number of literary traditions and schools, Duncan is often identified with the poets of the New American Poetry and Black Mountain College. Duncan saw his work as emerging especially from the tradition of Pound, Williams and Lawrence. Duncan was a key figure in the San Francisco Renaissance.

American poetry refers to the poetry of the United States. It arose first as efforts by American colonists to add their voices to English poetry in the 17th century, well before the constitutional unification of the Thirteen Colonies. Most of the early colonists' work was similar to contemporary English models of poetic form, diction, and theme. However, in the 19th century, an American idiom began to emerge. By the later part of that century, poets like Walt Whitman were winning an enthusiastic audience abroad and had joined the English-language avant-garde.
