* First's cube
* Locutus' cube
* Seven of Nine's cube
== By incident ==
===First contact cube ===
In 2365 Starfleet encountered the first known Borg cube in System J-25 when Q threw the Enterprise into that system. This event constituted the official first contact, although the Borg themselves had been encountered two hundred years before by the crew of and also by civilian researchers in the 2350s. 
The Borg cube encountered in 2365 dispatched two drones to the , which examined the ship's engineering spaces. The cube then attacked the Enterprise, slicing into the saucer section and using a tractor beam to extract components from three decks. Captain Picard had an away team, consisting of Riker, Data, and Worf, beamed aboard the Borg vessel in order to learn more about the Borg. The away team learned a great deal, but then the Enterprise had to retrieve the team after finding out that the Borg were telepathically using their collective hive mind to repair their damaged vessel. The Enterprise left at warp speed pursued by the Borg cube.
The Enterprise increased to maximum warp, but still had no success in escaping. Riker ordered them to arm photon torpedoes and Picard gave the order to fire, but the torpedoes had no effect. The Borg ship, after getting within firing range, fired a shield-draining missile twice and the Enterprise, with very low shields, fired torpedoes again, with the same result. After determining their weapons were useless, Picard pleaded with Q to send the Enterprise back into Federation space, which he did. It is unknown where the Borg cube went after Q helped the Enterprise escape. ()
The cube encountered at the end of the next year was said to have identical dimensions to this ship. ()
===Sector 001 cube ===
 
In 2373, this Borg cube attacked Earth much in the same manner as the previous cube from Wolf 359. The Battle of Sector 001 ended when this Borg cube was destroyed by a Starfleet armada using tactical knowledge of Captain Picard from his time as Locutus. The Borg Queen was on board this cube, and attempted to escape back in time using a Borg sphere. ()
===Nekrit Expanse cube ===
In 2368, this Borg cube was disabled by an electrokinetic storm within a nebular region of the Delta Quadrant, the Nekrit Expanse. With the majority of the Borg aboard the cube killed, eighty thousand surviving drones (freed from the Collective) fled to a nearby M-class planet. The derelict cube was later discovered by the in 2373 and subsequently boarded by its crew. It was later visited by Commander Chakotay who successfully reactivated the ship's neuroelectric generator, rejoining the surviving Borg into a new collective called the Borg Cooperative. The reactivation of the generator also reactivated the cube and its dormant drones, however the Cooperative ordered the cube to self-destruct before all its systems were fully operational.
The cube's complement of drones consisted of many Alpha and Beta Quadrant species including Humans, Romulans, Cardassians, Klingons, Farn, and Parein. It was the first Borg vessel encountered by the Voyager crew. ()
===Klingon space cube ===
A squadron of the Klingon Defense Force battled a Borg cube of the same type that engaged Starfleet in the Battle of Wolf 359 and suffered substantial losses. ()
===Two Borg cubes ===
In 2373, these two Borg cubes, which confronted Species 8472, were destroyed. ()
===Long-range probe cubes ===
In 2373, Voyager launched a long-range probe. Several months later, the probe encountered these two cubes and was assimilated. It was this encounter that proved Voyager had entered the heart of Borg space. ()
===Fifteen Borg cubes ===
In 2373, fifteen Borg cubes passed the USS Voyager in pursuit of Species 8472. One of these cubes stopped momentarily to scan Voyager with a polaron beam. All fifteen vessels were later destroyed by a Species 8472 bio-ship. ()
=== Sister ships to Seven of Nine's cube ===
As captain Janeway sought to contact the Borg in order to make her proposition, she found that besides Seven of Nine's cube, two other cubes were in orbit around the Borg planet Voyager arrived at. These two cubes were destroyed by the shock wave of the exploding planet, detonated by Species 8472, while trying to protect Seven of Nine's cube from destruction, in which they succeeded to their own detriment. ()
===Borg cubes in fleet ===
In 2374, a Borg fleet consisting of 312 ships, a number of which were cubes, were destroyed by Species 8472 in Matrix 010, Grid 19. ()
=== Cube encountered by Species 8472 ===
This Borg cube appeared to Tuvok in a flashback he experienced during a telepathic communication with a member of Species 8472, in 2374. ()
===Species 116 homeworld cubes ===
In 2374, a member of Species 116, Arturis, who blamed Captain Kathryn Janeway for the assimilation of his homeworld, tried to lure the crew of the into a trap. He disguised his ship as a Starfleet vessel, so he could get the crew of Voyager on board. However, his plan was discovered and he only managed to capture Captain Janeway and Seven of Nine before he activated the quantum slipstream drive and set a course for his former homeworld, inside Borg space. Voyager pursued them and managed to rescue Janeway and Seven. As the vessel emerged from slipstream, it was quickly surrounded by at least four cubes. Arturis and his ship were presumably assimilated. ()
===Species 10026 homeworld cubes ===
When Seven of Nine briefly returned to the Borg Collective in 2375, a fleet consisting of the Borg Queen's ship and two cubes left the unicomplex to assimilate Species 10026. Upon arrival they were attacked by 39 vessels armed with pulse weapons, which could penetrate their shields. With the unwilling help of Seven of Nine, the Borg were able to adapt and assimilated almost the entire species. ()
=== Unicomplex cubes ===
Multiple cubes were present at the Borg Collective's Unicomplex in 2375. ()
===Cube reduced to debris ===
In 2377, Voyager found a debris field, the remains of a damaged cube near the Yontasa Expanse. ()
=== Cubes near transwarp hub ===
Numerous cubes were located near the transwarp hub that located in a Delta Quadrant nebula. At least two were destroyed by Voyager. ()

===Cube in Grid 641 ===
This cube was directed to Grid 641 to surreptitiously track in 2378. () 
===Battle against the Romulans ===
These six cubes participated in a battle against twelve Romulan warbirds during the late 2370s. The battle was happened upon by the before the Federation starship hastily departing the battlefield. ( Season 1 opening credits)
===Battle with Pakleds against the Romulans and Klingons ===
Sometime around 2381, these four cubes along with two Pakled Clumpships participated in a battle against eight Romulan warbirds and six Klingon Birds-of-Prey. The Cerritos was also present, but hastily departed the battlefield after taking weapons fire from the Borg. ( Season 2 opening credits)
===Battle with Pakleds against the Romulans, Klingons, and a Crystalline Entity ===
Sometime around 2381, these four cubes along with two Pakled Clumpships participated in a battle against eight Romulan warbirds, six Klingon Birds-of-Prey, and a Crystalline Entity. The Cerritos was also present, but hastily departed the battlefield after taking weapons fire from the Borg. The Crystalline Entity also destroys one of the Borg cubes. ( Season 3 opening credits)
=== Cube encountered by USS Protostar ===
This disabled cube was encountered by the in 2384. ()
===Beta Quadrant wreckage ===
In an alternate timeline, in which was lost while using quantum slipstream drive, Starfleet Intelligence recovered a Borg temporal transmitter in the wreckage of a Borg cube in the Beta Quadrant sometime before 2390. ()
