Gustavo Miguel Alatriste (25 August 1922 – 22 July 2006)^[1] was a Mexican actor, director, and producer of films.

He was married from 1961 through 1967 to the actress Silvia Pinal. They had one daughter, actress Viridiana Alatriste (1963–1982).

He was married several other times, to actresses Ariadne Welter, and Sonia Infante (the latter for 18 years) and had more than 20 other children, most of them in Mexico city and Guadalajara. Multiple sons have his name.

He began his career producing Luis Buñuel's Viridiana (1961), which starred his then-wife, actress Silvia Pinal. The film, considered one of the greatest in Cinema of Spain^{[citation needed]}, was the first of three films by the trio.

In the eighties, Alatriste was named vice president of the Mexican CANACINE film organization.

Alatriste died of pancreatic cancer on 22 July 2006 in Houston, Texas, although it was not made public until July 25, leading to confusion about the true date. La Crònica de hoy gives the date and time of death as Saturday, 22 July at 11:45pm, according to Alatriste's ex-wife Sonia Infante. It was actually 11:45AM, according to medical records.
