Alfredo Valenzuela Puelma[1] (Valparaiso, 8 February 1856 – Villejuif, France, 27 October 1909), was one of Chile's best-known painters and one of the four artists known as the Great Chilean Masters.

At the age of twelve, he began attending the Academy of Painting (Santiago, Chile) where he learned from Ernesto Kirchbach and Juan Mochi.

During the last decade of the 19th century, when living in Valparaíso, he played an active role as an administrator at the Theater La Victoria, as well as managing art exhibitions.

His remains were later repatriated to Chile and honored at a grand ceremony held in the main hall of the National Museum of Fine Arts.

Throughout his productive career, he worked using oils and painted a very diverse range of subjects, such as landscapes, interiors, portraits, still lifes and especially nudes.
