The Toshiba T series comprises personal computers sold internationally by the Japanese electronics conglomerate Toshiba, under their Information Systems subsidiary (now known as Dynabook Inc.), from 1981 to 1995.

The T series began with desktop computers such as the T100 and T300, both of which were rebranded Pasopia models from Japan for United States markets.[1] Starting with the fast-selling Toshiba T1100 laptop, the vast majority of succeeding entries in the T series comprised portable computers, including laptops, luggables, and notebooks, as Toshiba had largely abandoned the international desktop market, where they had failed to gain much uptake.[2] The T prefix denotes models sold exclusively outside of Japan; within Japan, Toshiba sold these computers with the J prefix instead.[3]

Beginning with Toshiba's T1800 laptop in 1992, Toshiba began introducing brand names to go alongside certain T-series models (in the T1800's case, Satellite).[4] This practice continued until June 1995, when Toshiba's computer division imposed a nomenclature reset which removed the T prefix and dictated that all succeeding models have a brand name.[5]
