Elsa Gramcko (9 April 1925, Puerto Cabello — 1994, Caracas) was a Venezuelan abstract sculptor and painter. Her earlier works, which date from 1954, were geometric paintings, while her later works were more tachist in nature. While her earlier works consisted of mostly paintings, she expanded into sculpture and assemblage in the 1960s and 70s.
In 1959, José Gómez Sicre curated her first solo show at the Art Museum of the Americas in Washington D.C. She represented Venezuela in the 1959 São Paulo Art Biennial and in the 1964 Venice Biennale. In 1968 she was awarded the National Art Prize at the Official Salon of Venezuelan Art and in 1966 she became the first woman to obtain the first prize at the D'Empaire Salon held in Maracaibo, Zulia State, Venezuela. Her work is held in various private and public collections throughout Latin America and worldwide. Ida Gramcko, her sister, was an essayist and poet.
