Home Alone 3 is a 1997 American family comedy film directed by Raja Gosnell in his directorial debut, written and co-produced by John Hughes, and starring Alex D. Linz and Haviland Morris. A standalone sequel to Home Alone 2: Lost in New York (1992), it follows Alex Pruitt, an 8-year-old boy who defends his home from a dangerous band of international criminals working for a terrorist organization. It is the third film in the Home Alone franchise, and the first not to feature actor Macaulay Culkin, director Chris Columbus, or composer John Williams; Gosnell had previously served as editor on the first two Home Alone films. It is also the final film in the Home Alone franchise to receive a theatrical release.

The film was met with mixed reviews, with critics praising Linz's performance but criticizing the film's departure from the previous installments, including its themes and cast. Home Alone 3 was followed by a made-for-television standalone sequel, Home Alone 4, in 2002.
