The Neopets collectible trading card game is a spin-off of the popular virtual pet website, Neopets.com. Launched in 2003, this game is produced by Wizards of the Coast, a large trading card company that produces a variety of other trading card games. Neopets is aimed at a slightly younger and/or somewhat more female audience than other Wizards of the Coast offerings such as Magic: The Gathering. As with many other trading card games, there are two purposes to the trading cards; the first to collect the cards, and the second to play a devised game using the cards.

Neopets is a two player game, where each player has a play deck of at least 40 cards and a separate deck of at least 10 Basic Neopets. Players start with a single Neopet on the first turn, moving up to three by the third turn. These Neopets compete against opposing Neopets in four different arenas: Strength, Agility, Intelligence, and Magic. Winning a competition during a player's own turn allows the player to bank or draw a card; banking enough cards of sufficient value eventually leads to victory.
