Yeeks are a fictional race of goblin-like humanoids found in many roguelike games, such as Moria, Angband and ZAngband. Yeeks are described as "Strange small humanoid[s]" and can come in different colours depending upon what tribe they belong to. The most common yeeks are blue or brown but clear and black yeeks exist. The yeeks are ruled by their king Boldor and his son Orfax.

Yeeks are typically very easy monsters to defeat, in Moria at least. Folklore even holds that they are called "yeeks" because that is the sound they make if they are trod upon. Although black yeeks are unusually tough and master yeeks have some magic powers, there are no yeeks that normally require more advanced tactics than a few strokes with one's weapon. In the case of clear yeeks, who are invisible, it is nearly always possible to win by striking randomly or, if one is a mage, by firing an area effect spell at a nearby wall. Note that in Angband and later games yeeks are resistant to acid.
