Ju-On: The Grudge is a 2002 Japanese supernatural horror film written and directed by Takashi Shimizu. It is the third installment in the Ju-On series and the first to be released theatrically (the first two being direct-to-video productions). It stars Megumi Okina, Misaki Ito, Takashi Matsuyama, and Yui Ichikawa.

The first installment is a remake of Ju-On: The Grudge and follows a similar storyline to the Japanese film. The sequel, The Grudge 2, is not a remake and follows a unique storyline, albeit still borrowing some plot elements from several Japanese predecessors.
