Grid 005 is the Borg spatial designation for a region of space in the Delta Quadrant containing the Krenim Imperium.

In various alternate timelines created by the activities of the Krenim weapon ship, it also contained the Zahl, Garenor, Ram Izad, Mawasi, Nihydron, Rilnar, Malkoth, and Alsuran civilizations. The USS Voyager traversed this grid in 2374. (VOY: "Year of Hell", "Year of Hell, Part II")
