A klongat (Klingonese: tlhonghaD) is an animal native to Qo'noS, which is larger than a targ, and more difficult to subdue. (Star Trek: IKS Gorkon novel: Honor Bound) When held in a restricted space, such as a pen, a klongat would pace its territory restlessly. (TOS eBook: Mere Anarchy: The Blood-Dimmed Tide)

The gizzard of a klongat is a common Klingon food. Bekk Goran often ate klongat gizzards with zlim'kach; others, such as Tabona, felt it improper to serve the two together. (KE novel: A Burning House)
