T'Garas was a female Vulcan diplomat in the 24th century.

She began her career as an aide to Federation Councillor T'Latrek. In late 2380, she was appointed as ambassador to the newly-formed Imperial Romulan State. In early 2381, T'Garas informed Empress of the Imperial Romulan State Donatra of Professor Sonek Pran's planned mission to Achernar Prime, and sent the Empress a copy of a monograph Sonek had written years earlier on Alidar Jarok.
