Antonio Lorenzo (Madrid, 1922 - 2009) was a prominent Spanish painter and printmaker associated with the avant-garde and abstraction from the 1950s. Trained at the Central School of Fine Arts in Madrid, he evolved from a figurative style to lyrical abstraction, creating works that explore utopian themes, symbolic references to human progress, and the interplay between form and machine.

He was a member of the Grupo de Cuenca alongside Antonio Saura, Fernando Zóbel, Gerardo Rueda, Eusebio Sempere, and Gustavo Torner, and contributed to the foundation of the Museum of Spanish Abstract Art in Cuenca, where he also worked as a curator and printmaking educator.

Renowned for his work in painting and printmaking, Lorenzo exhibited internationally, including participation in the Venice Biennales of 1964, 1966, and 1972, and his works are part of major collections worldwide, establishing him as a key figure in Spanish abstract art.
