Sharknado is an American six-film made-for-television science fiction action comedy horror disaster film series released by Syfy between 2013 and 2020.

The series stars Ian Ziering as Fin Shepard and Tara Reid as April Wexler—a husband and wife who encounter "sharknadoes", tornadoes filled with sharks, wherever they go.A freak hurricane hits Los Angeles causing man-eating sharks to be scooped up in water spouts and flood the city with shark-infested seawater.

Bar-owner and surfer Fin (Ian Ziering) sets out with his friends to rescue his estranged wife, April (Tara Reid), and their teenage daughter, Claudia, before the "sharknado" reaches them.

An ad after the film promotes a Twitter campaign offering fans the chance to decide her fate with the hashtags "#AprilLives" or "#AprilDies", with the results revealed at the start of Sharknado 4, which first aired on Syfy on July 31, 2016.

A write-up in Bloody Disgusting in February 2018 said: "In his quest, Fin fights Nazis, dinosaurs, knights, and even takes a ride on Noah's Ark.
