Despite his logical Vulcan nature, Spock has had quite a few love interests during his tenure as a character in the Star Trek franchise. First introduced in Star Trek: The Original Series, Spock became arguably the most popular and well-known character in the franchise, appearing in multiple series and movies and played by many different actors since his debut in 1966. Spock's struggle with his half-Vulcan, half-human nature is one that Star Trek audiences seem to find endlessly fascinating, and his complicated relationship with his more human emotions has been revisited repeatedly for almost every iteration of his character.
Although Spock almost always tried to stick to the Vulcan way of life and suppress his emotions, there were times when they got the better of him. When this happened, one of the ways it manifested was in a romantic encounter, something that was usually the antithesis of Spock's personality and storylines and thus very enjoyable for Star Trek audiences to watch. While Spock hasn't had a record-breaking amount of romances during his time in the Star Trek franchise, all of them have been memorable in some way or another, and perhaps more interesting when they do happen because of their infrequency.
8 T'Pring
T'Pring is arguably Spock's greatest Star Trek love interest, considering that she was once his fiancé. In Star Trek: TOS season 2, episode 1, "Amok Time", Spock (Leonard Nimoy) was forced to return to T'Pring (Arlene Martel) on Vulcan when he began undergoing the symptoms of Pon Farr, the Vulcan drive to mate. While TOS made it seem like the couple wasn't particularly well-acquainted despite their marriage being arranged as children, Star Trek: Strange New Worlds season 1 revealed that Spock (Ethan Peck) and T'Pring (Gia Sandhu) maintained a surprisingly loving relationship, choosing to become engaged as adults and striving to make their relationship work despite Spock's commitment to Starfleet.
Unfortunately, by the time of Spock's Pon Farr in TOS, the two had grown apart, and their relationship ended after T'Pring chose the kal-if-fee ritual during their wedding, forcing Spock to fight Captain Kirk (William Shatner) to Kirk's supposed death. At the time, Spock seemed less disturbed by the dissolution of his marriage than by the fact that he had apparently killed his Captain, but Strange New Worlds introducing the idea that Spock and T'Pring were close cast the end of their relationship in a much sadder light. After the events of "Amok Time", T'Pring was never seen or mentioned in Spock's life again.
7 Christine Chapel
Nurse Christine Chapel is Spock's second-biggest Star Trek love interest, and like T'Pring their relationship has been explored in both TOS and Strange New Worlds. Unfortunately for Nurse Chapel (Majel Barrett), the relationship in TOS was portrayed as largely one-sided, with Chapel harboring extremely strong feelings for Spock while Spock was unwilling to or uninterested in acknowledging them. Although "Amok Time" hinted that Spock might return Chapel's feelings under different circumstances, her love for him remained unrequited throughout TOS, although it was frequently acknowledged in episodes.
However, retconned Spock and Chapel's (Jess Bush) relationship into something much closer. While season 1 largely stuck with the unrequited love angle, the trailer for Strange New Worlds season 2 showed Spock and Chapel sharing quite a ionate kiss and Spock displaying an emotional celebration afterward. If Spock and Chapel were indeed closer during their early years of working on the USS Enterprise, then Strange New Worlds has once again put a much more tragic spin on one of Spock's biggest romantic subplots, given Chapel's pining after Spock during TOS.
6 Leila Kalomi
Leila Kalomi (Jill Ireland) was one of Spock's one-off love interests during Star Trek: TOS. A botanist, Leila met and fell in love with Spock prior to their on-screen meeting. Spock refused to it any feelings for Leila initially, but upon the Enterprise's arrival at Omicron Ceti III, Leila deliberately infected Spock with the spores of the pod plant, causing him to experience emotions and profess his love for her in return. Spock intended to stay with Leila, but Captain Kirk was able to help Spock regain control by provoking him into anger, and Spock's more logical side reasserting itself ended his and Leila's relationship for good.
5 The Romulan Commander
Although never given a name, the Romulan Commander (Joanne Linville) proved to be an intriguing Star Trek romance for Spock. The two met when the Enterprise was sent on a secret mission to Romulan space to steal a cloaking device. Captain Kirk and Spock orchestrated a ruse to get aboard the Romulan Commander's ship, and while a disguised Kirk successfully retrieved the cloaking device, Spock allowed the Commander to seduce him in an attempt to distract her. Although Spock was simply going along with the plan, he did state at the end of the episode that his feelings for the Commander weren't entirely fake, hinting that he found her intriguing.
4 Zarabeth
Zarabeth (Mariette Hartley) was Spock's final on-off love interest in Star Trek: TOS. Zarabeth and Spock met when she saved him and Dr. McCoy (DeForest Kelley) after they accidentally traveled through a time portal. Because of the portal's effects, Spock began to regress evolutionarily and started displaying stronger emotions, causing him to fall in love with Zarabeth. However, Spock and McCoy learned that if they stayed, they would both die due to the time portal's effects. After some convincing, Zarabeth led them back to the portal's entrance, and she and Spock parted ways unhappily. Once back in the future, Spock's feelings for Zarabeth faded as his mind returned to normal.
3 Saavik
Spock and Saavik were never officially romantically involved, but an intense scene in Star Trek III: The Search for Spock makes her an undeniable addition to Spock's love interests. During The Search for Spock, Saavik (Robin Curtis) mated with Spock to keep him from dying during the Pon Farr he experienced while rapidly aging on the Genesis Planet. The film only implied that the two had been intimate, but there were plans for Saavik to be pregnant with Spock's baby in subsequent movies. These plans were ultimately scrapped, and Saavik and Spock's relationship never progressed further, although the two were married in a few non-canon Star Trek novels.
2 Nyota Uhura
Spock (Zachary Quinto) and Uhura (Zoë Saldaña) were the main romantic couple in the Star Trek reboot films, which began with Star Trek (2009). Although Uhura (Nichelle Nichols) occasionally flirted with Spock on Star Trek: TOS, their relationship was never anything more than colleagues. Star Trek (2009) chose to make Spock and Uhura a couple, however, a decision that was somewhat controversial for a variety of reasons and ultimately handled badly. Because of the reboot films, Uhura is perhaps Spock's third-biggest love interest across the entire Star Trek franchise, although T'Pring and Nurse Chapel are considered in a much more favorable light.
1 Why Spock Never Married In Star Trek
There are several possibilities as to why Spock never married in Star Trek. Part of the reason is likely because romance was so incongruous with his character, given that the human form of romantic love was something he could never quite express except under the influence of some outside force. Ultimately, Spock became married to his work for Starfleet, first as an officer and then as an ambassador for the Federation. Spock's efforts to reunite the Vulcan and Romulan people consumed his attention for much of his later life, which likely would have made it hard for him to have a meaningful relationship with anyone, even another Vulcan.
