The Iremal Cluster was a star cluster located within the Alpha or Beta Quadrants. The Klingons knew it as the qul'mIn star cluster. It was known to be a sensor blind spot, having properties that scrambled both long and short range sensors.

In 2268, it was used to mask the deployment of the USS Sagittarius from the cargo hold of the Federation freighter SS Ephialtes from the Klingons and Romulans. (VAN novel: Storming Heaven)
