| Character | Actor | Episodes |
|---|---|---|
| Description | ||
| Tactics Officer | Peter Parros | A Matter of Honor (TNG) |
| Klingon officer serving aboard the IKS Pagh in 2365. He escorted William Riker to see Captain Kargan, but kept looking askance at the commander because he'd never seen a human before. Later, in the mess hall, he also admitted that he never knew humans had a sense of humor. Regarding his family, his mother was still living, but his father was killed in battle at Tranome Sar. | ||
| Tahna Los | Jeffrey Nordling | Past Prologue (DS9) |
| Bajoran terrorist who comes aboard Deep Space Nine asking for asylum only to escape Cardassian pursuit and begin work on his next attack | ||
| Taibak | John Fleck | The Mind's Eye (TNG) |
| Romulan officer and scientist who successfully "conditioned" Geordi La Forge to kill Klingon governor Vagh of Krios, although the assassination failed. Taibak served aboard Commander Sela's Warbird in late 2367, and his "brainwashing" efforts were part of a larger Romulan plot to disrupt the alliance between the Federation and the Klingon Empire. | ||
| Enabran Tain | Paul Dooley | The Wire (DS9) recurring thereafter |
| Former head of the Obsidian Order and the father of Elim Garak | ||
| Juliana Tainer | Fionnula Flanagan | Inheritance (TNG) |
| A Soong-type android created in the image of Noonien Soong's dying wife, Juliana Soong; at Juliana's death, Noonien transferred his wife's consciousness into the android who awoke believing she was Juliana Soong; later left Noonien, married Pran Tainer and took up residence on planet Atrea IV | ||
| Tal | Jack Donner | The Enterprise Incident (TOS) |
| Subcommander of the Romulan fleet that brackets the Enterprise when she "strays" into Romulan space. After Captain Kirk steals the cloaking device and beams back aboard the Enterprise, Tal sets off in pursuit. When his Commander orders him to destroy the Federation starship, he attempts to comply, but fails because Mr. Scott managed to successfully install the cloaking device and render the Enterprise "invisible." | ||
| Tal Celes | Zoe McLellan | The Haunting of Deck Twelve (VOY) Good Shepherd (VOY) |
| Bajoran sensor analyst on Voyager, assigned to Astrometrics. Despite her evident insecurity, she later demonstrated bravery, refusing to abandon Janeway in danger. ("Good Shepherd") | ||
| Taleen | Nancy Youngblut | Displaced (VOY) |
| Nyrian who explained a new customized habitat to the Voyager crew, as part of the Nyrian's forced relocation scam. | ||
| Talok | Todd Stashwick | Kir'Shara (ENT) |
| Romulan agent who posed as a Vulcan major for many years, working with the radical Administrator V'Las of the Vulcan High Command to force reunification between their two peoples. A "very long time" before 2154, Talok served under T'Pol in the Tomed mission. In 2154, V'Las ordered Talok to eradicate the remaining Syrrannites. Talok tracked down Jonathan Archer in Vulcan's Forge and attempted to take the Kir'Shara, but Archer escaped. After V'Las was removed and the Vulcan High Command disbanded, Talok's position was compromised and he was forced to leave Vulcan.[1] | ||
| Tarcassian Razor Beast | None (Only discussed, never seen.) | Imaginary Friend, Rascals (TNG) |
| Imaginary friend from the childhood of the enigmatic female El-Aurian bartender Guinan, who ran Ten Forward, the lounge aboard the USS Enterprise-D. The Tarcassian razor beast was a winged, furry animal noted for its spiny wings, and its loping way of locomotion. When Guinan was troubled, she'd talk to it, and she enjoyed imagining that she was curling up on its warm belly. | ||
| Taris | Carolyn Seymour | Contagion (TNG) |
| Romulan subcommander of the IRW Haakona. She spotted and chased the USS Yamato NCC-71807 throughout the Romulan Neutral Zone before finally witnessing its destruction due to systems failures. When confronted almost immediately by the Enterprise-D, she denies any involvement in the Yamato's destruction and orders Captain Jean-Luc Picard to leave the Neutral Zone. Later, at Iconia, her "excuse" for having followed the Enterprise-D was to claim the planet for the Romulan Star Empire, but when Commander William Riker points out that neither side can claim anything in the Neutral Zone, she again orders the starship to leave, or else she'll destroy it and the Away Team on Iconia. In truth, Taris is deeply frustrated; earlier, the Haakona tapped into the Yamato's log as it was being transmitted to the Enterprise-D, and has now become crippled by Iconian "malware." When Picard steps onto her ship from the Iconian portal, she blames him for sabotage, but seems satisfied that he'll die when her ship autodestructs. Picard, however, is beamed back to the Enterprise-D, and Riker shares the "memory wipe" solution that Geordi La Forge developed with Taris.[2] | ||
| Taurik | Alexander Enberg | Lower Decks (TNG) |
| Vulcan ensign and junior engineer aboard the Enterprise-D. His ideas for improving warp drive operation rankle La Forge at first, but La Forge later sees the merit in Taurik's suggestions and invites him to help test them. | ||

| EPS control specialist killed in the Xindi attack on the Enterprise in the Azati Prime system | ||
| Tebok | Marc Alaimo | The Neutral Zone (TNG) |
| Romulan commander who, in 2364, made the first "official" contact with the Federation after more than 53 years of Romulan isolation. He was primarily charged with discovering why several Romulan outposts along the Neutral Zone had disappeared, but the re-emergence was also orchestrated to show off the Romulans' massive new D'Deridex class "warbird" starships. Tebok ominously proclaimed "we are back" to Captain Picard. | ||
| Temarek | Elkanah J. Burns | The Vengeance Factor (TNG) |
| Temarek was an Acamarian Gatherer and a member of Clan Lornak. During treaty negotiations in 2366, he discovered the corpse of Volnoth, who was killed by Sovereign Marouk's servant Yuta because of ancient clan rivalries. | ||

| Clark Terrell | Paul Winfield | WOK |
| Captain of the starship Reliant. Controlled by Khan Noonien Singh via a Ceti eel, forcing him to nearly kill Admiral Kirk. Rather than murder a fellow Starfleet officer, he committed suicide.

| Thelev | William O'Connell | Journey to Babel (TOS) |
| An Orion agent posing as a member of the Andorian delegation to the 2267 "Babel" conference. His mission is to create mutual suspicion among the Federation ambassadors aboard the Enterprise.

| Toddman | Leon Russom | The Die Is Cast (DS9) |
| Starfleet vice admiral at Starfleet Security in 2371. After Enabran Tain launched a joint Obsidian Order/Tal Shiar attack on the Founders' homeworld, Toddman ordered Commander Benjamin Sisko to evacuate Starbase Deep Space Nine of all nonessential personnel and put the USS Defiant NX-74205 on standby alert. He believed that when the Jem'Hadar inevitably counterattacked, they wouldn't be too particular about their targets. Toddman denied Sisko permission to take the Defiant into the Gamma Quadrant and look for Odo; Sisko's top priority was to guard Bajor. Later, after learning that Sisko went anyway, Toddman decided to forgo any courts-martial, but, with tongue in cheek, promised to either prosecute or promote Sisko if he pulled a stunt like that again.[3] | ||
