Alice, Sweet Alice (originally titled Communion) is a 1976 American psychological slasher film co-written and directed by Alfred Sole, and starring Linda Miller, Paula Sheppard, and Brooke Shields in her film debut. Set in 1961 New Jersey, the film focuses on a troubled adolescent girl who becomes a suspect in the brutal murder of her younger sister at her First Communion, as well as in a series of unsolved stabbings that follow.

Inspired by Nicolas Roeg's Don't Look Now (1973) and the films of Alfred Hitchcock, writer-director Sole devised the screenplay with Rosemary Ritvo, an English professor who was his neighbor. At the time, Sole had been working as an architect restoring historic buildings in his hometown of Paterson, New Jersey, and several properties he had worked on were used as shooting locations. Filming took place throughout the summer of 1975 in Paterson and Newark.

The film premiered at the Chicago International Film Festival under its original title, Communion, in November 1976, and was released under this title in London in September 1977. After being acquired by Allied Artists, it was re-titled Alice, Sweet Alice, and released in the United States on November 18, 1977. Another theatrical re-release occurred in 1981 under the title Holy Terror, which marketed the popularity of Shields after her performance in Louis Malle's Pretty Baby (1978). While not prosecuted for obscenity, the film was seized and confiscated in the UK under Section 3 of the Obscene Publications Act 1959 during the video nasty panic, and was controversial in Ireland due to its apparent anti-Catholic themes.

In the years since its release, Alice, Sweet Alice has gained a cult following and is considered a contemporary classic of the slasher subgenre in critical circles. It has also been the focus of scholarship in the areas of horror film studies, particularly regarding its depictions of Roman Catholicism, child emotional neglect, and the disintegration of the American nuclear family.
