Jack Spicer was an American poet often identified with the San Francisco Renaissance. In 2009, My Vocabulary Did This to Me: The Collected Poetry of Jack Spicer won the American Book Award for poetry. He spent most of his writing life in San Francisco.

The term San Francisco Renaissance is used as a global designation for a range of poetic activity centered on San Francisco, which brought it to prominence as a hub of the American poetry avant-garde in the 1950s. However, others felt this renaissance was a broader phenomenon and should be seen as also encompassing the visual and performing arts, philosophy, cross-cultural interests, and new social sensibilities.
