Tomie (Japanese: 富江) is a Japanese horror manga series written and illustrated by Junji Ito. It centers on a mysterious, beautiful woman named Tomie Kawakami. The manga was Ito's first published work that he originally submitted to Monthly Halloween, a shōjo magazine in 1987, which led to him winning the Kazuo Umezu award.

Tomie has been adapted into a live-action film series with nine installments to date, an anthology television series released in 1999, and a streaming television series was in development for Quibi before the service was shut down.

Tomie Kawakami, identified by her sleek black hair and a beauty mark below her left eye, acts like a succubus, possessing an undisclosed power to make any man fall in love with her. Through her mere presence, or through psychological and emotional manipulation, she drives these people into jealous rages that often lead to brutal acts of violence. Men kill each other over her, and women are driven to insanity as well—though there are some who are strong enough to resist her. Tomie is inevitably killed time and time again, only to regenerate and spread her curse to other victims, making her effectively immortal. Her origins are never explained, though it is suggested by some older men in the series that she has existed long before the events of the manga.

Each story showcases various characters that encounter Tomie in her many (often hideous) forms, with some having their own arcs or returning in later chapters. Tomie's regenerative abilities (partly fuelled by cannibalism and assimilation) are also showcased: aside from recovering quickly from gruesome and seemingly mortal wounds, she can also replicate herself by sprouting unnaturally from any part of her body, whether it be from severed limbs, organs, or even her spilled blood. Radiation accelerates her healing/regeneration process. Her cells are also capable of transforming a victim into a Tomie via an organ transplant. Multiple characters are even driven to dismember her corpse, unwittingly allowing more Tomie copies to grow and spread throughout the world. Even locks of her hair are dangerous, burrowing into its victims' brain to possess them, and eventually killing them when it grows wildly within the body. It is also shown that even if Tomie's body is not injured, her body will attempt to sprout another Tomie through tumorous growths, usually when she is emotionally stressed. Some Tomie copies, however, cannot stand one another; one is seen killing another personally, while others order it done through the boys they seduce/enslave. Fire is the only known method to destroy a Tomie for good, though only if the flesh is completely carbonized.

The next story arc, beginning as a prequel, reveals that a baby girl can grow naturally into a Tomie via a blood injection and that she can age if she has not yet copied herself. The man responsible for these injections is a horribly burnt stranger—once a supermodel disgraced by a Tomie in his past—who seeks revenge by making one of these "natural" Tomies old and ugly. He manages to encase a Tomie named "Ayaka" in a block of cement with the help of Ayaka's older sister. The two then wait for many years—endlessly hearing her tormented cries—before finally breaking the block, revealing that Tomie had somehow escaped through a tiny crack, her apparent wailing being nothing more than wind blowing through the hollow block.

An arc released exclusively with the DVD release of the Junji Ito Collection, titled Tomie: Takeover, features Tomie encountering a man capable of body-switching, who finds her various abilities difficult to handle.

A four-page crossover arc with Souichi Tsujii, titled Souichi Possessed, was released in 2018. In the story, the titular's Souichi's older brother Koichi tells a younger Tomie of his attempted mischief of a brother's encounter with a different elderly Tomie, the arc serving as the prologue to a larger confrontation between the pair, as the younger Tomie requests an introduction.

Tomie is published by Asahi Sonorama and appeared as a serial in the manga magazine Monthly Halloween from 1987 to 2000. Tomie received one bound volume in February 1996, titled Tomie no kyōfu gaka (富江の恐怖 画家, lit. Tomie of Fear: Painter). Two volumes were collected into the overarching series The Junji Ito Horror Comic Collection (伊藤潤二恐怖マンガCollection) as volume 1 and 2 of the series. Asahi Sonorama released an omnibus volume in February 2000 titled, Tomie Zen (富江 (全)). ComicsOne released both volumes on April 1, 2001, with flipped artwork (read left-to-right).
