Koloth, played by William Campbell, is a Klingon character in the fictional Star Trek universe who appears in the original series episode "The Trouble with Tribbles", the animated series episode "More Tribbles, More Troubles", and the Star Trek: Deep Space Nine episode "Blood Oath".

As the captain of the Klingon vessel IKS Gr'oth, Koloth faces James T. Kirk at spacestation K-7 during the 2268 Sherman's Planet affair depicted in "The Trouble with Tribbles". According to Jadzia Dax in the Deep Space Nine episode "Trials and Tribble-ations", Koloth always regretted never facing Kirk in battle. Koloth once defeated T'nag and his army with only colleagues Kang and Kor, according to Kor's tale 2372 in the Deep Space Nine episode "Once More Unto the Breach", later feasting on the leader's heart; he personally attacked T'nag's flank with only a disruptor and a bat'leth, killing two dozen men out of vengeance.

In 2290, Kor, Kang, Koloth and Curzon Dax pledged a blood oath to avenge the deaths of the sons of the three Klingon captains, the offense committed by the Albino. They nearly caught him at Galdonterre, but one of their subspace messages was intercepted and he, once again, was able to escape.

After decades of searching, Kang learned of the whereabouts of the Albino, in 2370, on the planet Secarus IV. Kang traveled to Secarus IV and discovered his compound. The Albino knew immediately of his arrival and invited the trio to a "fair fight" and one last glorious battle. Kang would contact both Kor and Koloth for a rendezvous on Deep Space 9, in preparation of their final attempt to complete their lifelong quest.

Koloth has not been a contender in any CBUB matches.
