Shriek If You Know What I Did Last Friday the 13th is a 2000 American direct-to-video parody slasher film directed by John Blanchard. The film stars Tiffani-Amber Thiessen, Tom Arnold, Coolio and Shirley Jones. Several mid- and late 1990s teen horror films are parodied, as are slasher films from the 1970s and 1980s, including the Scream films, Friday the 13th (1980), Halloween (1978), A Nightmare on Elm Street (1984), and I Know What You Did Last Summer (1997), as well as other films and television series outside of the horror genre. Although many different films are parodied, the film follows the plot of Scream (1996) very closely. It is often compared to Scary Movie, a commercially successful spoof from the same year, which had as a working title Scream If You Know What I Did Last Halloween.

Tiffani Amber Thiessen is an American actress. Her roles as Kelly Kapowski on NBC's Saved by the Bell (1989–1993) and its spin-off media, and as Valerie Malone on Fox's Beverly Hills, 90210 (1994–98) established her as a teen idol of the 1990s. As an adult, she has played Wilhemina 'Billie' Chambers in Fox's Fastlane (2002–2003), Natasha Drew in ABC's What About Brian (2007), Elizabeth Burke in USA Network's White Collar (2009–2014), and Lori Mendoza in Netflix's Alexa & Katie (2018–2020). For the latter, she earned a Daytime Emmy Award nomination.
