T'Pris (full name at death: T'Sai T'Pris Aduna Sepel kiran) was a female Vulcan, the daughter of Sirak and T'Dar, who served on board the USS Enterprise in 2253. While serving on the Enterprise, she met a young Mr. Spock, who had just recently been promoted to Lieutenant and posted to the Enterprise. After some time, the two began a romantic relationship, and Spock briefly considered dissolving the bond he had with his betrothed back home, T'Pring. She accompanied Spock on a mission to retrieve Vulcan's Glory.
Shortly after recovering the Vulcan's Glory, T'Pris was murdered by Lieutenant Daniel Reed, a human crewmember with 1/8 Vulcan blood, whose maternal great-grandmother had been disgraced when the Glory had originally been lost.
