Magic: The Gathering (MTG; also known as Magic) is a trading card game created by Richard Garfield.

First published in 1993 by Wizards of the Coast, Magic was the first trading card game produced and it continues to thrive, with approximately twenty million players as of 2015^. Magic can be played by two or more players in various formats, the most common of which uses a deck of 60+ cards, containing no more than 4 of a single card with the exception of basic land cards, either in person with printed cards or using a deck of virtual cards through the Internet-based Magic: The Gathering Online, on a smartphone or tablet, or other programs.

Each game represents a battle between wizards known as "planeswalkers", who employ spells, artifacts, and creatures depicted on individual Magic cards to defeat their opponents. Although the original concept of the game drew heavily from the motifs of traditional fantasy role-playing games such as Dungeons & Dragons, the gameplay of Magic bears little similarity to pencil-and-paper adventure games, while having substantially more cards and more complex rules than many other card games.

New cards are released on a regular basis through expansion sets. An organized tournament system played at an international level and a worldwide community of professional Magic players has developed, as well as a substantial secondary market for Magic cards. Certain Magic cards can be valuable due to their rarity and utility in game play, with prices ranging from a few cents to thousands of dollars.
