A Thief Cache is a barrel in The Elder Scrolls V: Skyrim that can be looted for various items. The Thief Caches in Riften appear immediately after the Dragonborn has joined the Thieves Guild (being the Guild Master is not required). The "Special" missions assigned by Delvin Mallory must be completed for each specific hold in order for the other Thief Caches to appear.
The Thief's Cache shadowmark is present on the side of the Barrel.
At higher levels, most Thief Caches may contain a Daedric Dagger with a random enchantment, some Daedric Arrows and gems, and a way of lockpicking, be it a potion of lockpicking or a large amount of lockpicks.
