Knockback is an enchantment applied to swords and spears that increases melee knockback.

Knockback can be obtained from enchanting tables, drops from mobs that have spawned in a raid,‌^{[Bedrock Edition only]} books obtained by fishing, monster room chests, librarian villagers, and non-village structure loot.

Knockback increases horizontal melee knockback by 2.586 blocks per level. The base knockback of attacks without the enchantment and without doing a sprint-knockback attack is 1.552 blocks, causing an attack with Knockback II to deal 6.724 blocks of knockback.​^{[more information needed]} Knockback also increases vertical melee knockback from 0.8125 blocks to 1 block, regardless of the level of enchantment. Sword sweep attacks are affected by the Knockback enchantment. The increased knockback from this enchantment stacks with sprint-knockback attacks.

Spear charge attacks done using a spear in the offhand‌^{[Java Edition only]} do not apply Knockback.^[1] If an attack from a Knockback weapon is blocked by a shield, the knockback effect doesn't apply in Java Edition but does in Bedrock Edition. By use of commands to increase the level of enchantment beyond II, the enchantment has diminishing returns when attacking players but not when attacking mobs. In Java Edition, players can hit armor stands back with the Knockback enchantment, but not in Bedrock Edition. Damage immunity provides immunity to the Knockback enchantment.

If Knockback is applied to a trident by use of commands or an anvil in Creative, the enchantment functions when using the weapon's melee attack but not when using its ranged attack.

• Squid and glow squid are resistant to knockback when outside of water.
• Iron golems, wardens and shulkers are completely unaffected by knockback.
• Agents and NPCs are invulnerable and completely unaffected by knockback.
