Aquis Submersus (Latin for Drowned in the Waters) is a painting by the German dadaist and surrealist Max Ernst created in 1919.

Influenced by the Italian metaphysical art it is one of Ernst's earliest works showing surrealistic accents.

In the pool, the picture shows a possibly female or childish body in an upside-down position with only the waist and legs above the water level.

In the foreground is an armless statue-like figure that appears to have been made out of clay, throwing a shadow in the direction of the pool, similar to another shadow originating from outside the picture.

The person looks away from the pool and bears a handlebar mustache resembling that of Ernst's father, but also has features which could be interpreted as female.
