Corey Alex Seaver (born April 25, 1999) is an American director, writer, and former actor. He commenced acting in June 2017 as a recurring background high school student on the second season of the Netflix teen drama 13 Reasons Why (Anonymous Content). About halfway through production, his first film appearance arrived as a Pier 39 pedestrian in the 2018 Marvel film Ant-Man and the Wasp.

Following this, opportunities began piling up and, upon completion of aforementioned series' third season, Seaver obtained speaking roles in student and short subjects, as well as taking scene study courses at the Beverly Hills Playhouse. His repertoire includes The OA, Always Be My Maybe and A Taiwanese Tale of Two Cities (Netflix), Wheels of Fortune and A Christmas Mystery (ESX), Earth Mama (Park Pictures), Fremont (Blue Morning), I'm a Virgo (Media Res), Freaky Tales (eOne), The Lost Son Returns As the Duke (ReelShort), The Tutors (Galatea TV), and Artificial (Heyday).

Whether it be an encyclopediac knowledge of the cinematic art, a fascination with cult films, or co-creating director/actor filmographies on the Internet Archive, Seaver is well versed in pop culture, has an enthusiasm for musical theatre, and watches a wide variety of film genres (he's very active on Letterboxd, under the username 'chief_mccloud'). He has penned various short stories since junior high, and has only in the past few years advanced to scripts.

In July 2021, he began working for Cinemark, a profession he'd desired for many years, and stayed with the company for three years, only choosing to depart after three consecutive location shutdowns. In March 2026, he found new theater employment for a smaller indie chain.

Three months later, in June 2026, after nearly a year without a gig, Seaver ceased pursuing professional acting, citing no interest in being associated with the seemingly increasingly pro-AI Screen Actors Guild. He plans to direct, write, produce and star in his own work, with the intent to turn his short film manuscript into a miniseries.
