The Grudge 2 is a 2006 American supernatural horror film directed by Takashi Shimizu and written by Stephen Susco. The film is the sequel to The Grudge (2004) and the second installment in the American The Grudge film series. The film stars Arielle Kebbel, Amber Tamblyn, Jennifer Beals, Edison Chen, Sarah Roemer, and Sarah Michelle Gellar. As stated by Shimizu, the film is not a remake of any Japanese film and follows a different storyline. 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 film was announced after the release of the previous film in October 2004, due to its financial success. Shimizu was announced to return as director in January 2005 and casting begun on December, with the announcement of Gellar returning. The film was shot entirely in Japan, with Tamblyn performing re- shoots in Chicago, Illinois.

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 over $70.7 million worldwide against a production budget of $20 million. A sequel, The Grudge 3, was released direct-to-video on May 2009, while a sidequel, The Grudge , was theatrically released on January 2020.
