Gerardo Diego Cendoya (October 3, 1896 – July 8, 1987) was a Spanish poet, a member of the Generation of '27.

Diego taught language and literature at institutes of learning in Soria, Gijón, Santander and Madrid.

He began his poetic work with El romancero de la novia (1920).

After discovering the Chilean poet Vicente Huidobro, founder of the Creationist movement, Diego became one of the most enthusiastic followers of Creacionismo.

The extensive poetic work of Diego has always varied between the themes and expressions of Vanguardism and the more classical structures of poetry.
