The following is a glossary of terms used in card games. Besides the terms listed here, there are thousands of common and uncommon slang terms. Terms in this glossary should not be game-specific, but apply to a wide range of card games played with non-proprietary packs. It should not include terms solely related to casino or banking games. For glossaries that relate primarily to one game or family of similar games, see Game-specific glossaries.

A card game is any game that uses playing cards as the primary device with which the game is played, whether the cards are of a traditional design or specifically created for the game (proprietary). Countless card games exist, including families of related games. A small number of card games played with traditional decks have formally standardized rules with international tournaments being held, but most are folk games whose rules may vary by region, culture, location or from circle to circle.
