James Mercer Langston Hughes (February 1, 1902 – May 22, 1967) was an American poet, social activist, novelist, playwright, and columnist from Joplin, Missouri.

He was one of the earliest innovators of the then-new literary art form called jazz poetry. Hughes is best known as a leader of the Harlem Renaissance. He famously wrote about the period that "the negro was in vogue", which was later paraphrased as "when Harlem was in vogue".
