The Grudge 2 is a 2006 American supernatural horror film directed by Takashi Shimizu and written by Stephen Susco. The film is a sequel to The Grudge (2004) and the second installment in the American The Grudge film series, based on the Ju-On franchise created by Shimizu. It is the sixth and last Ju-On or The Grudge film directed by Shimizu. The film stars Arielle Kebbel, Amber Tamblyn, Jennifer Beals, Edison Chen, Sarah Roemer, and Sarah Michelle Gellar, the latter reprising her role from the first film.

Like its predecessor, the film features a plot that is told through a nonlinear sequence of events and includes several intersecting subplots. It follows Karen's younger sister Aubrey coming to Japan after finding out about Doug's death, a schoolgirl named Allison being haunted by the ghosts of the Saeki family after entering the house with two of her classmates, and a young boy named Jake whose apartment building is haunted by the ghosts.

The Grudge 2 was released in the United States on October 13, 2006, by Sony Pictures Releasing. The film received negative reviews from critics and grossed $70.7 million worldwide. A sequel, The Grudge 3, was released direct-to-video in May 2009.
