Toško Čelo was attested in written sources in 1376 as Vaystemek (and as Vaistenekk in 1414, Faisten Hirn in 1453, and Na Verhu, Navrchu vel Turskczel, and Taustutschel in 1763-87). The modern name of the settlement literally means 'Tošč face': the noun čelo (otherwise 'forehead' in Slovene) refers to a vertical or steep rocky cliff face below a summit and the adjective toško is related to Mount Tošč (1021 m) to the west (originally based on a dialect form of the adjective tolst 'fat'). The original meaning 'fat' is also reflected in the medieval German names of the settlement, containing the Middle High German word veiz(e)t 'fat'.
