Gustavo Cochet (May 6, 1894 – July 27, 1979) was a painter, engraver, and writer who worked in Barcelona and Rosario.

His mother was of mestizo heritage, and his father was French, a teacher in a rural elementary school located between Esperanza and San Jerónimo Norte, in the province of Santa Fe, Argentina.

Cochet spent his first years in elementary school in the countryside, and his father was then transferred to Carlos Pellegrini and then to Maciel, both small towns in Santa Fe.

Cochet became more politically involved afterwards, and from 1935 participated in the Iberian Anarchist Federation, speaking and reflecting on the rights of artists in what he considered an era of revolution.

He returned to Argentina in 1939, and was named Professor of Painting at a new school in the city of Santa Fe, where he lived and taught until 1946.
