Atom Egoyan CC (/ɛˈɡɔɪən/; Armenian: Ատոմ Եղոյեան, romanized: Atom Yeghoyan; born July 19, 1960) is an Armenian-Canadian filmmaker. One of the most preeminent directors of the Toronto New Wave, he emerged during the 1980s and made his career breakthrough with Exotica (1994), a hyperlink film set in a strip club. He followed this with his most critically acclaimed film, The Sweet Hereafter (1997), an adaptation of the Russell Banks novel of the same name, for which he received Academy Award nominations for Best Director and Best Adapted Screenplay.

Egoyan's other significant films include The Adjuster (1991), Ararat (2002), Where the Truth Lies (2005), Adoration (2008), Chloe (2009), Devil's Knot (2013), and Remember (2015). His works often explore themes of alienation and isolation, featuring characters whose interactions are mediated through technology, bureaucracy, or other power structures. His films often follow non-linear plot structures, in which events are placed out of sequence in order to elicit specific emotional reactions from the audience by withholding key information. Many of his films also draw on his experiences as a first-generation immigrant, and as a member of the Armenian diaspora.
