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 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, the only one not set during Christmas (takes place right after Christmas), and the first not to feature actor Macaulay Culkin, director Chris Columbus, or composer John Williams; Gosnell had 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 received 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 sequel, Home Alone 4: Taking Back the House, in 2002.
