Enrique Buenaventura Juan Seoane Ros (Lima, January 12, 1915 – July 26, 1980) was a Peruvian modernist architect of the 20th century.^[1]

Seoane was born in Lima on January 12, 1915, to parents Buenaventura Guillermo Seoane García and Rosario Ros Gutiérrez. He studied at the Colegio de La Inmaculada and followed architecture courses at the National School of Engineers, predecessor of the National University of Engineering (UNI).^[2]

He graduated as an engineer-architect in 1944 and was a professor at the Department of Architecture at the UNI and at the Federico Villarreal National University.^[2]

He was a supporter in favor of a modern style of architecture that would replace the old-fashioned French-style of Lima, and supported—but did not sign—a manifesto that was published in El Comercio and El Arquitecto Peruano in 1947 that supported this movement.^[2]
