Card Sharks is an American television game show. It was created by Chester Feldman for Mark Goodson-Bill Todman Productions. The game features two contestants who attempt to predict the outcome of survey questions to gain control of a row of oversized playing cards, then determine whether the next card drawn is higher or lower. The title Card Sharks is a play on the term "card sharp", a person skilled at card games.

The concept has been made into a series four separate times since its debut in 1978, and also appeared as part of CBS's Gameshow Marathon. The show originally ran on NBC from 1978 to 1981 with Jim Perry hosting. The show returned and ran from 1986 to 1989 on CBS with Bob Eubanks as host, accompanied by a syndication production with Bill Rafferty. Gene Wood was the announcer in both the 1970s and 1980s. Another syndicated production aired in 2001 with Pat Bullard as host and Gary Kroeger as announcer. A revival hosted by Joel McHale aired on ABC from June 2019 to July 2021. Each production has featured various assistants to handle the playing cards.

Reruns of the show aired on Game Show Network from the channel's start in 1994 until 2018. Reruns currently air on Buzzr.
