"A Supermarket in California" is a poem by American poet Allen Ginsberg first published in Howl and Other Poems in 1956. In the poem, the narrator imagines visiting a supermarket in California where he finds Federico García Lorca and Walt Whitman shopping. Whitman, who is also discussed in "Howl", is a character common in Ginsberg's poems, and is often referred to as Ginsberg's poetic model. "A Supermarket in California", written in Berkeley and published in 1956, was intended to be a tribute to Whitman in the centennial year of the first edition of Leaves of Grass.
