A tripwire hook is a block that can be used to detect entities (players, mobs, items, etc.) when part of a tripwire circuit is passed through.
To remove a tripwire hook, mine it. Tripwire hooks can be broken instantly using any tool, or without a tool.
A tripwire hook will also be removed and drop itself as an item if:
- its attachment block is moved, removed, or destroyed
- water flows into its space in Java Edition and Legacy Console Edition
- a piston tries to push it or moves a block into its space
A tripwire hook will be destroyed without dropping itself as an item if lava flows into its space.

Tripwire hooks can be obtained as a "junk" item from fishing.
Four tripwire hooks are generated naturally in each jungle temple.
Tripwire hooks can be found in 30.5% of pillager outpost chests in stacks of 1–3.
Tripwire hooks can be used as crafting ingredients or as redstone components.

A tripwire hook can be used to detect mobs, items, and other entities over a large area.
- To place a tripwire hook, use the Place Block control.
- A tripwire hook can be attached to the side of any full solid block, with the inexplicable exception of blocks of redstone and observers.
- In order to function correctly, a tripwire hook must be part of a "tripwire circuit": a straight line of blocks consisting of a block with a tripwire hook attached to it, a "tripwire line" (1 to 40 blocks of tripwire), and a second tripwire hook attached to another block, with both tripwire hooks facing the tripwire.
- To place tripwire, use the Place Block control with a string. Tripwire in a valid tripwire circuit has a short hitbox (0.09375 or 3/32 blocks high, with the bottom 0.0625 or 1/16 blocks above the block below), while tripwire not in a valid tripwire circuit has a taller hitbox (0.5 blocks high, bottom not raised).
- A tripwire hook in an invalid tripwire circuit appears "folded", while a tripwire hook in a valid tripwire circuit appears extended straight. Tripwire lines from separate tripwire circuits can be placed next to each other (in parallel), above each other, and even intersecting each other.
- A tripwire hook in a valid tripwire circuit activates when certain entities (players, mobs, items, etc.) intersect the tripwire hook's tripwire line "hit box" (but not the tripwire hook itself), and deactivates when all entities leave or are removed from the tripwire line.
- Entities that will not activate a tripwire circuit include thrown potions, some arrows, fireworks, thrown ender pearls, and thrown eyes of ender.
- A tripwire hook also activates for 5 redstone ticks (0.5 seconds, barring lag) when any of its tripwires are destroyed, except when shears are used to destroy the tripwire.
- Breaking the tripwire hook, or breaking the block it is attached to, does not generate a pulse.
- While active, a tripwire hook appears to move downwards and it:
- powers any adjacent redstone dust to power level 15, including beneath the tripwire hook
- powers any adjacent redstone comparators or redstone repeaters facing away from the tripwire hook to power level 15
- strongly powers its attachment block to power level 15
- activates any adjacent mechanism components, including above or below, such as pistons, redstone lamps, etc.
- Tripwire produces no power itself, but its state change can be detected with an observer.
- Although destroying tripwire with shears will not activate a tripwire hook, it will change the tripwire hook's block state (its "attached" state from
false) which can be detected with an observer.
In Bedrock Edition, a tripwire hook's block data stores its orientation, connection status, and activation status:
A two-bit field storing a value from 0 to 3:
|0x4||If set, the tripwire hook is connected and ready to trip ("middle" position).|
|0x8||If set, the tripwire hook is currently activated ("down" position)|
|Name||Default value||Allowed values||Description|
|attached||True if the tripwire hook is connected to a valid tripwire circuit.|
|facing||The direction in which the tripwire hook juts out from the block it is attached to.|
For example, a tripwire hook facing north will be attached to a block to its south.
|powered||True if the tripwire hook is active.|
|1.3.1||May 28, 2012||Dinnerbone released a series of cryptic tweets, starting with "I think I'm taking a big liking towards adventure maps. It's starting to show in my choice of new blocks." He hinted at shears being used to disable the tripwire, then posted a series of images before revealing the name. Afterwards, he posted a video to reveal the functionality of the tripwire and finally credited the idea to his fiancee MissMarzenia.|
