Alternate timelines were altered versions of a single universe. There were several methods of temporal manipulation that could create an altered version of a timeline.
- A temporal incursion into the past could cause an alternate chain of events to unfold. However, in the cases where the time travel event was part of a predestination paradox, an alternate timeline was not created. (DS9: "Trials and Tribble-ations")
- Time travel to the future of a timeline could create an alternate future, where the time traveler had never returned back to the past from the future. Such was the case, for example, when the USS Enterprise-C traveled from 2344 to 2366 through a temporal rift. (TNG: "Yesterday's Enterprise"; DS9: "The Visitor"; ENT: "Shockwave", "Shockwave, Part II")
- When objects were pushed out of the space-time continuum, they were also erased from history, creating an altered timeline, where the object never came into being. Such was the case with the effect of the main weapon of the Krenim weapon ship and destroying the interspatial parasites that had infected Captain Jonathan Archer in the 22nd century. (VOY: "Year of Hell"; ENT: "Twilight")
Starfleet officers were forbidden to cause changes in the timeline by the Temporal Prime Directive, or even to discuss their knowledge of future events. (VOY: "Shattered") By the 28th century, changing the timeline had become more universally illegal after the Temporal Accord was established. (ENT: "Cold Front") By the 29th century, Starfleet had taken it on as a mission to use time travel as a means of upholding the integrity of the timeline by fixing changes in the past. It was also Starfleet policy by then to integrate different versions of people into one, when several coexisting ones appeared due to paradoxes and time travel. (VOY: "Relativity")
While the prime timeline was usually restored by operatives from the 29th to the 31st centuries, in some cases, the influence of alternate timelines remained as a part of the chain of events in the prime timeline. Spock for instance would not have learned that he had to travel to the past to save himself from being killed by a Le-matya when he was seven years old, had he not accidentally traveled to an alternate timeline, where he had not yet saved himself. (TAS: "Yesteryear") Warnings, temporal incursions and information of alternate futures were also an integral part of the prime timeline. Such was the case, when Captain Jean-Luc Picard shared his experiences of the future shown to him by Q, to his crew in 2370, allowing them to make different life choices. (TNG: "All Good Things...") USS Voyager was rescued and aided by it's crew members from the future. In 2375, a transmission from Harry Kim from an alternate 2390 averted the crash landing of the Voyager. In 2378, technology and assistance from Admiral Kathryn Janeway from an alternate 2404 saved the ship from a long and disastrous journey through the Delta and Beta Quadrants. (VOY: "Timeless", "Endgame")
Alternate realities
Different versions of a timeline also sometimes coexist as parallel universes. Most active temporal anomalies allow interaction between two different alternate timelines for a moment, making them parallel realities in relation to one another.
- Harry Kim considered an alternate reality as one possible cause for his sense of déjà vu and familiarity to a region of space in the Delta Quadrant, until the Taresian retrovirus was discovered to be the actual cause. (VOY: "Favorite Son")
- Time travel to the past through the red matter created black hole by the Romulan mining vessel Narada resulted in the creation of an alternate reality. (Star Trek)
- A brief experience with a parallel reality was theorized to be one possibile cause for Tuvok's breakdown in 2373 over memories of events Tuvok had not experienced. The cause was later on discovered to be a memory virus unknowingly transmitted to him from Lieutenant Commander Dmitri Valtane, in 2293. (VOY: "Flashback")
- Temporal causality loops create independent parallel fragments of time, inside which time of the universe repeats itself. From outside the loop, it appears as if the things inside had simply vanished from the space-time continuum. For people inside to loop the memories from previous loops begin to assert themselves as a sense of déjá vu, and eventually clearer memories. (TNG: "Cause and Effect")
- In 2370, Q allowed Picard to shift his consciousness between three parallel timelines, one in the past, one in the present and one in the future from Picard's point of view, in order for him to create an anti-time eruption. The eruption was linking these universes together. When it was sealed into subspace, the coexisting timelines also collapsed. (TNG: "All Good Things...")
- In 2371, radiation poisoning and the temporal energy emissions of an artificial quantum singularity of a Romulan Warbird allowed Miles O'Brien to jump between the prime and an alternative timeline in which Deep Space 9 was destroyed. At least during some of the jumps the two timelines coexisted. (DS9: "Visionary")
- The quantum singularity lifeforms were native to a parallel space time-continuum. They utilized temporal apertures to travel between continuums and delivered their embryos to mature in nests inside the gravity wells of quantum singularities in our universe. The adult beings of the species were capable of taking humanoid form and were unaffected by temporal fractures. (TNG: "Timescape")
- The race of the alien, who took the shape of Cosimo, existed in temporal inversion folds of the space-time matrix. The folds were parallel time streams visible as temporal anomalies intersecting the prime reality. Inside the folds, reality remained unaffected by changes in the timeline. It was possible to utilize a fold in a similar way to a quantum fissure and to exchange one's consciousness with an alternate possible timeline version of oneself. (VOY: "Non Sequitur")
- It was also possible to create pockets, where a previous timeline continued, while the timeline of the rest of the universe was changed. Such technology as a subspace bubble, a subspace isolation field, temporal shielding and the wake of a temporal vortex kept any enveloped object in a pocket with its own timeline. The Guardian of Forever was also capable of maintaining the time vortex planet in its original timeline. (TNG: "Timescape", DS9: "Past Tense, Part I"; VOY: "Year of Hell"; Star Trek: First Contact; TOS: "The City on the Edge of Forever")

Apocrypha
- According to the Star Trek: Myriad Universes story Places of Exile by Christopher L. Bennett in the 2008 novel of the series, Infinity's Prism, the concept of quantum realities is synonymous with all types of alternate timelines. According to the novel 2008 novel Fearful Symmetry by Olivia Woods, the mirror universe is also a parallel quantum universe, further suggesting that even trans-dimensional realms are alternate timelines.
- The game Star Trek: Armada features the USS Premonition, (USS Premonition at Memory Beta, the wiki for licensed Star Trek works) a starship came from an alternate future where the Borg controlled most of the Alpha Quadrant. Captain Thaddius Deming of the Premonition hoped to warn the Federation of a coming Borg invasion in time to prevent the Borg victory. With the help of Captain Jean-Luc Picard of the USS Enterprise-E, and after making two further temporal incursions, the Premonition's mission was a success and she returned back to the future.
