Promises Written in Water is a 2010 experimental drama film written, directed, edited, and produced by Vincent Gallo. The film stars Gallo, alongside Delfine Bafort, Sage Stallone, Lisa Love, and Hope Tomaselli.

The third feature film to be directed by Gallo, it premiered at the Venice Film Festival, alongside his short film The Agent (2010). The film received polarized and mostly negative critical reviews; though a minority of positive reviews called it one of the year's best films. It was nominated for the Golden Lion.

After just two festival screenings, the film became unavailable for the general public to watch, per Gallo's wishes. Since 2010, the film has never been screened or made available to watch for the general public.
