Battle items (バトルアイテム, Batoru Aitemu?) are consumable items that can be equipped to party members and used in the field. They typically restore a party member's HP or MP. In Kingdom Hearts, Kingdom Hearts II, and Kingdom Hearts 358/2 Days, equipped battle items can be used by selecting the Items command in the Command Menu. In Kingdom Hearts II and 358/2 Days, equipped items can be set to shortcuts for easy access.

In Kingdom Hearts and Kingdom Hearts II, only a certain amount of battle items can be taken into combat at once, as each party member is restricted to the amount of item slots that they have. Each character begins with a certain amount of item slots, while Sora, Donald, and Goofy gain more by achieving bonuses.
In Kingdom Hearts Chain of Memories, battle items take the form of item cards, as part of the card-based combat system. Instead of healing a character, item cards restore used attack and magic cards to their deck. Unlike most other card types, item cards cannot be reloaded once used.
In Kingdom Hearts Birth by Sleep, Kingdom Hearts Re:coded, and Kingdom Hearts 3D: Dream Drop Distance, battle items take the form of item commands, as part of the Deck Command combat system. Unlike other command types, item commands can be used a limited number of times, and they are equipped in limited quantities to a slot in the Command Deck; however, they do not have a cooldown period after each use. Item commands may restore a character's HP or other gauges, heal status effects, or activate Command Styles.
Camp items (キャンプアイテム, Kyanpu Aitemu?) are consumable items that must be used in the menu.
