Chainmail Helmet is a head-slot armor piece in Minecraft that grants 2 armor points (one full armor icon) and 165 durability, the same durability as an Iron Helmet but with less protection. Unlike most gear, Chainmail Helmet has no survival crafting recipe — players obtain it through journeyman-level Armorer villager trades, as rare loot in generated structure chests, or from zombies and skeletons that spawn already wearing it and can drop the helmet on death. Chainmail Helmet works identically in both Java Edition and Bedrock Edition.

Chainmail Helmet can be enchanted on an enchanting table or anvil with Protection IV, Respiration III, Aqua Affinity, Thorns III, Unbreaking III, and Mending, making it viable early-game head protection when iron or diamond is scarce. Because there is no chainmail ingot, you repair a Chainmail Helmet by combining two helmets on an anvil or grindstone, or by using the Mending enchantment to restore durability with experience orbs. Builders and collectors also keep Chainmail Helmet for its distinctive grey woven texture, which stands out from solid iron or gold helmets on armor stand displays.
