Mastocal (Sigma Kinna IX) was the ninth planet in the Sigma Kinna star system in the Klingon Empire. It was the only Class M world in its system, and was the location of a major Klingon military base in the mid-23rd century.

The Klingons annexed Mastocal during the Four Years War, and began construction on the base shortly after the war's end. It was completed in 2259, becoming the largest Klingon Defense Force base built at that time, and marking the Empire's return to a state of war-readiness equal to what it had been before the recent conflict with the Federation.

From the base on Mastocal, the Klingons planned to spread their influence into Federation space. However, the Organian Peace Treaty put an end to those plans in 2267. Nevertheless, the KDF continued to build up Mastocal in preparation. The base eventually grew to cover the entire planet, and housed manufacturing plants in addition to the barracks and training facilities. No ship construction yards were present, however, though extensive repairs could be made to any Klingon vessel in either the orbital or ground-based docking facilities.
