Luis A. Martinez (Ambato, June 23, 1869 – November 26, 1909) was an Ecuadorian writer, painter, politician, and agriculturist. His novel A la costa (1904) is a masterpiece of Ecuadorian literature, and is one of the earliest works of realism in Ecuador. He was also a painter; some of his best paintings are housed outside of Ecuador: Two are in the United States Library of Congress, two in the Modern Art section of the Vatican Museum, and one is in Rio de Janeiro, Brazil. He was an opponent of the government of Eloy Alfaro (President of Ecuador in 1895-1901, 1906-1911) and fought against the liberal guerillas of the 1890s.
Martínez had 11 siblings, two of which were the writers Anacarsis Martínez and Augusto N. Martínez. In 1896, Martínez married Rosario Mera Iturralde, the daughter of the poet Juan León Mera (1832–1894), who wrote Cumanda (Ecuador’s first novel) and the Ecuadorian national anthem. They had two children, the novelist Blanca Martínez Mera de Tinajero, and the painter Luis Edmundo Martínez Mera (1903-1976).
