Nicomedes "Nick" Marquez Joaquin (May 4, 1917 – April 29, 2004) was a Filipino writer and journalist best known for his English-language short stories and novels.
His father, Leocadio Joaquin, worked as an attorney at the Laguna Court of First Instance, where he met his second wife, Salome, Joaquin's mother.
Joaquin was already experimenting with his literary voice at a young age. He published his first English poem, Don Quixote, at the age of 17, in the literary section of the pre-World War II Tribune, where he worked as a proofreader.
Later, in 1937, he published his first short story, "The Sorrows of Vaudeville," in the Sunday Tribune Magazine, telling the story of the vaudevilles in Manila, a city he was enamored with. Serafin Lanot, a writer and editor, accepted it.
He was well-known as a historian of Spain's brief Golden Age in the Philippines, a writer of folk Roman Catholic short stories, a playwright, and a novelist. Joaquin's works were written in English.
