|-| Nyota Uhura=
Spock and had a relationship that was established prior to the start of their careers on board the Enterprise. Spock was openly confronted by Uhura regarding her getting assigned to the even though she was qualified to serve aboard the , to which Spock replied that his decision had been just "an attempt to avoid the appearance of favoritism." By Uhura insisting he change her posting to the Enterprise, he was indeed persuaded to do so.
While on duty aboard the Enterprise, Spock and Uhura maintained a formal professional relationship – Spock usually addressing her by her rank and surname – with the exception of some moments where the nature of their feelings for one another was displayed or hinted by their actions. Shortly after they arrived on the ship, Spock supported and extolled Uhura's abilities before Captain Pike.
One moment of affection between them was just after Spock realized Nero had created a black hole in the planet Vulcan. This incident impacted on Spock's relationship with Uhura, especially since he decided to beam down to the Vulcan surface himself, in an attempt to save his parents and the Vulcan High Council. When a concerned Uhura called him by name and not by rank, he paused, in the midst of a crisis, to explain to her what he was about to do and offered further explanation.
After Vulcan was destroyed by Nero, Spock was at one point pursued by Uhura off the bridge and into a turbolift, where she comforted him, the two lovers kissing and embracing each other.
After Spock lost control and attacked Kirk, he looked to Uhura, ashamed of what he'd done. He shared another look with her as he walked off the bridge after giving up command.
Later, their relationship revealed itself to Kirk and Scott when they witnessed Spock and Uhura kissing in the transporter room. There, Spock also called her by her first name, "Nyota". ()
A year later, Uhura accompanied Spock to Nibiru before he was rappelled from a shuttle into a volcano, to prevent it from wiping out the Nibirans. The ash damaged the shuttle and snapped the wire, forcing Uhura and to leave him. Uhura swam back to the Enterprise, which was hidden underwater. She was distraught to learn ash from the volcano would prevent the Enterprise from transporting Spock back aboard, and to hear Spock explain he would prefer to die activating the cold fusion device than violate the Prime Directive. 
Later, when the Enterprise was tasked with hunting down terrorist John Harrison, Uhura hinted to Kirk in the turbolift that she and Spock were having relationship troubles. While on a shuttle to Qo'noS where Harrison was hiding, Uhura and Spock got into an argument, where she accused of him of being too ready to sacrifice himself for a mission and not caring how she would feel if he died. Spock acknowledged that since his mother's death, he had been closing himself to such thoughts about how she would feel since he had experienced those feelings, specifically because he did care. Later, after getting back to the Enterprise, the two shared a reconciliatory kiss.
After Harrison revealed he was Khan Noonien Singh, Spock asked Uhura to contact his older parallel universe counterpart on New Vulcan for information. Uhura managed to make contact although the ship was outside of normal range of communication with his location.
When Kirk died in attempt to save the ship and his crew, Uhura encouraged Spock to beam down to go after and capture Khan, who had crashed the Vengeance into San Francisco. However, when McCoy discovered that a blood transfusion from Khan could heal Kirk, Uhura volunteered to beam down saving Spock from having his head crushed by Khan in the same manner in which he had killed admiral Marcus. As Spock took the opportunity to gain the advantage in the fight and kill him, Uhura stopped Spock by informing him they need Khan alive to save Kirk. ()
Almost 3 years into their five years mission, Spock and Uhura were still a couple but they experienced a brief time-out in their relationship as a consequence of him starting to doubt his purpose in Starfleet, and wondering if he maybe owed a debt of duty to his species, and he should have therefore left the ship to join the rest of the vulcans on New Vulcan helping them rebuild their race.
When the crew got to Starbase Yorktown, Uhura tried to give him back his mother's vokaya necklace that he had gifted her, but a visibly sad Spock declined the offer insisting her to keep it.
Shortly after leaving Yorktown, the Enterprise was destroyed by Krall's attack leaving Spock stranded on planet Altamid with while Nyota Uhura, and the rest of the Enterprise crew minus the Captain, Pavel Chekov and Montgomery Scott, got captured by Krall and held prisoner at his base.
While talking with McCoy, an injured Spock regretfully confessed that before their ship got destroyed and they lost the crew, he had wanted to discuss things more with Uhura but was interrupted by news about Ambassador Spock dying that affected him unexpectedly, and further persuaded him to leave Starfleet in spite of his feelings for her. 
Later on after he was beamed aboard the by Kirk and Scotty, Spock realized that if Uhura was still wearing his Vokaya amulet, Chekov could track the unique Vulcan mineral (that emitted a harmless radiation) and find her (and thus the rest of the crew held prisoner by Krall). When the group made a plan to free the crew, a still injured Spock insisted to participate to the mission because Uhura was in the base too. In spite of his condition, both Kirk and McCoy allowed him to go with them acknowledging their friend's need to be there due to his relationship with the Lieutenant.
Once him, McCoy and Jaylah got to the base as planned and the two men freed the crew, Hikaru Sulu informed Spock that Uhura unfortunately wasn't with them anymore because she had been taken by Krall shortly before him and McCoy got there. 
Spock then went looking for her alone but he got attacked by two Swarm soldiers and fell to the ground in pain, only to get saved by Uhura who helped him stand up and asked what he was doing there. When Spock answered that he clearly was there to rescue her (noticing the irony of the situation), Uhura smiled pleased by his care for her and his efforts. 
Later, when Spock volunteered to pilot one of the swarms ships to try to stop Krall from destroying Yorktown, Uhura expressed concerns over him being still hurt for his injury to which Spock replied he respected and appreciated her concerns.
After the events on Altamid put his life into perspective, Spock realized that his place was with his friends just like the other Spock (who had a picture of his crew mates still with him when he died). Having decided to stay, him and Uhura, whose feelings for one another had not changed, reprised their relationship. 
At the party for Jim's birthday, Uhura, who openly wore his Vokaya necklace again, teased Spock saying that she thought he had a mission report to make, to which he replied that he did, but he thought that being with her would be more pleasing (implying he changed his original evening plans, putting work aside, and went to the party to spend time with her). 
Later, Spock, Uhura and their friends observed the new Enterprise under construction.
Spock's actor Zachary Quinto said that part of Spock's existential crisis in the movie is about how conflicted he feels between his duty towards the other vulcans to help them repopulate, and his love for Uhura. He said that in spite of them not being "at the height of relationship bliss" in this film, theirs is an ongoing relationship where the two of them "love each other deeply and they want each other to be happy, to be fulfilled, to serve their purpose, and to realize their potential." 
Uhura actress Zoë Saldana extremely appreciated how "human" and realistic Uhura's romance with Spock was portrayed as being. "I like that the characters gave [Spock actor] Zac and me an incredible subject and story to build upon," she enthused. (Star Trek Magazine Movie Special 2016, p. 44) }}
