Love Streams is a 1984 American film directed by John Cassavetes, in what would be his final independent feature and penultimate directorial project. The film tells the story of a middle-aged brother (Cassavetes) and sister (Gena Rowlands) who find themselves relying on one another after being abandoned by their loved ones.

The film was entered into the 34th Berlin International Film Festival where it won the Golden Bear.

Undergoing a messy divorce from a husband, and daughter, who are tired of her continuously overwrought emotional states, Sarah Lawson visits her brother Robert Harmon, an alcoholic playboy and writer. Robert is in a tenuous relationship with Susan, a professional singer, although he carefully avoids any real emotional commitment to anyone. Robert, who has not seen his son since birth, is visited by his ex-wife, who forces him to take care of their eight-year-old for 24 hours.

Robert's son is terrified by the hedonistic, decadent, womanizing world of his father and begs to be taken home following an overnight trip to Las Vegas filled with gambling and prostitutes. After dropping him off, Robert is beaten up by the boy's stepfather, after which his son testifies his love for Robert.

Fleeing the scene, Robert returns home to take care of his sister, his "best friend." Sarah tries with some success to curb the nihilistic self-destruction of Robert's life and simultaneously deal with her own depression and divorce. She buys him some farm animals in the hope he can give his love to them; Robert struggles between his intense desire to protect his sister and the challenge of accepting her freedom as the necessary cost of love. Finally, after a bizarre dream of being in an opera with her husband and daughter, Sarah feels ready to resume her life and possibly even get her family back, or not. Before Sarah walks away from the house in the middle of a storm as Robert looks on, he hallucinates that the dog she gave him has turned into a naked man. Robert laughs hysterically.

Love Streams is based on the 1980 play of the same name by Ted Allan, but the correlation between the screenplay and the play is minimal. In the stage production, the role of Robert Harmon was played by Jon Voight; Cassavetes took this role for the film version.

The visual style of the film is decidedly different from Cassavetes's other works; it contains no hand-held camera work (a trademark of his visual style). Much of it was shot inside Cassavetes' home.

Love Streams was originally released with a running time of 141 minutes. It was briefly available on videotape in the mid 1980s in a version cut to 122 minutes by the distributor; one scene was edited and several unusual visual effects (the insertion of black leader and jump cuts) were removed. In 2003, it was released on DVD in France (along with A Child Is Waiting) in its entirety. The 141-minute version received an American DVD and Blu-ray release for the first time in 2014 as part of The Criterion Collection.
