"The Love Song of J. Alfred Prufrock" is a work by which poet?

"The Love Song of J. Alfred Prufrock" is a seminal work by T. S. Eliot, widely recognized as one of the most important modernist poets of the 20th century. This poem, published in 1915, is notable for its innovative stream-of-consciousness style and fragmented structure, which reflects the complexities of modern life and the inner turmoil of its speaker, J. Alfred Prufrock. Eliot’s use of imagery and allusions creates a depth that invites readers to explore themes of indecision, alienation, and the passage of time.

The other poets listed, while significant in their own rights, are not the authors of this particular work. Katherine Mansfield is known for her short stories and her contributions to modernist literature, particularly through her compact and impactful narratives. Dylan Thomas is celebrated for his lyrical poetry, often rich in sound and emotion, but does not share the same thematic preoccupation as Eliot in "Prufrock." James Joyce, primarily recognized for his groundbreaking novels such as "Ulysses," also experimented with stream-of-consciousness but is not connected to Eliot's poem in any direct context. Thus, T. S. Eliot is unmistakably the correct choice for this question.
