Since the beginning of Minecraft's development, there have been a number of features added to the game that have no actual use. Some of these features are leftover from removed features, or simply placeholders for new features.
Note that this page only documents features that are currently in the game. See removed features for feature previously in the game that were unused.
Giants are an unused mob added in classic. They appear to be a giant zombie. Giants have no AI and only spawn when the light level is greater than 11 and less than 8. They can be summoned using the
The skeleton horse is a type of horse which can only be spawned using commands. It drops a single bone when killed.
The zombie horse is a type of horse which can only be spawned using commands. It drops a single rotten flesh when killed.
The unused potions can be seen in the inventory GUI files but some effects are not present. However, in 1.4.2 the custom potions feature was introduced. It is the only way to access the unused potion effects.
These potions can only be obtained using
/give, and have no effect when you drink them. This implies these are unused base potions.
There are also potions that cannot be brewed, and give you status effects not intended to be received by potions; e.g. Wither, Nausea. Again, these can only be obtained through custom potions.
A more detailed list can be found at Potions.
Various status effects remain unused in the game. They can be obtained using
/effect or potion NBT data, but have no way of being obtained other than that.
Blindness is a status effect which creates thick black fog around the player.
During the 1.6 snapshots, the health boost status effect was added. It boosted the player's hearts for a temporary time. It could be obtained from eating a golden apple.
In a later snapshot, golden apples give the player absorption instead of health boost, but the effect was still left in the game.
Loops were unused sounds, found in the game files, and were possibly meant for when the player is in a specific type of location (i.e., in caves, woods, the ocean and beside a waterfall).
They were found in
.minecraft/resources/sound/loops/, and could be converted to reveal four loops, of birds chirping, cave chimes, ocean and waterfall noises.

Calm4.ogg was a music file (alongside the other tracks) that was beta-tested and created by Notch himself.
It consists of an up-beat, battle-like tune. A part of the song has Notch saying "Mojang Specifications" in a slowed-down voice.
The track was released around Alpha 1.1.1 (Seecret Saturday 10), but it is unknown when and why it was omitted from the downloaded game files. As such, players who had the game while the song was still in it will continue to hear it being played, as the game will play any song in the
Various textures located in minecraft.jar remain unused.
Paeonias are an unimplemented block that was replaced by the two block high peonies.
There was only one screenshot of the block released by Jeb. When held into the hand, you hold it up level to your shoulder. Its texture can still be found called flower_paeonia.png.

In Legend of the Chambered (an abandoned RPG that Notch made), there was a quiver item available to be picked up as loot. Notch reused the sprite from that game and put it in Minecraft, albeit flipped horizontally.
Quivers are obtainable in the Pocket Edition using hacks. However, these quivers do nothing but freeze the game when used as they are an "empty" item using the quiver texture.

On May 21, 2012, Jeb released a screenshot of himself testing the trading system. At this time, what would become emerald ore in 1.3.1 was ruby ore. The previous ruby texture remains in the ruby.png file. It is unknown if the texture will ever be used. Dinnerbone stated in a forum post that they went with emeralds instead of rubies at the last minute because he is color-blind and he had a hard time spotting the difference between ruby ore and redstone ore.
