The IKS Gr'oth was a Klingon D7-class battle cruiser that was in service with the Klingon Imperial Fleet in the mid-23rd century. In 2268, the Gr'oth was under the command of Captain Koloth. The starship's first officer was Korax.
In that year, after spending five months in space, the Gr'oth entered Federation space and demanded shore leave rights at Deep Space K-7. It left the station with an engine room full of tribbles. (TOS: "The Trouble with Tribbles"; DS9: "Trials and Tribble-ations")

Background information Edit
The Gr'oth was not identified by name or seen in the original version of "The Trouble with Tribbles". The episodes "Trials and Tribble-ations" and the 2006 remastered version of "The Trouble with Tribbles" identified the ship orbiting K-7 to be a D7. "Trials and Tribble-ations" was the source of the ship's name. According to the script for the episode, the pronunciation for Gr'oth was "grrr-OTH". 
The old-fashioned D7 model was built by Greg Jein specifically for DS9's special 30th anniversary tribute to The Original Series. While faithful to the original D7 model, Jein took liberties with the Gr'oth, including enhanced details similar to those of the K't'inga-class starship. The model was also painted with a vaguely greenish hue, similar to the color scheme of "future" Klingon starships. (Star Trek Encyclopedia (4th ed., vol. 1, p. 313))
According to Star Trek: Voyager writer Mike Sussman,  dialogue for the seventh season episode "Prophecy" was written with the intent of reusing the studio model of the Gr'oth. A K't'inga-class CGI model was used instead, resulting in an apparent discontinuity.
The Starships RPG sourcebook gives its registry as IKC-4175.
According to Star Trek: Star Charts (p. 65) and Stellar Cartography: The Starfleet Reference Library ("Federation Historical Highlights, 2161-2385"), there was a system named Gr'oth, which might be the possible origin for the name of this starship, in the Beta Quadrant. The system's primary was a M-class star. It was the site of a historic battle.
