Stress Is Three (Original title: Stress-es tres-tres) is a 1968 Spanish road drama film directed by Carlos Saura.

The film stars Geraldine Chaplin and Fernando Cebrián as a troubled married couple.

Saura noted, "At the root of it, I had the sense that in Peppermint Frappé I was very constrained by story and I wanted to unbind myself.

Fernando (Cebrián) is a successful industrialist; however, he is dismayed that his personal life does not reflect his glittering career.

He is insecure about his faltering marriage to Teresa (Chaplin), who he believes is having an affair with his best friend, Antonio (Galiardo).
