Tit Labijen (otpr. 100 pr. Kr. - 17 Ožujka 45. pr. Kr.) bio je Cezarov legat i bliski prijatelj iz Galskih ratova. Za vrijeme Cezarovog građanskog rata, Labijen otkazuje lojalnost Cezaru i prelazi na stranu Pompeja.[1] Poginuo je u Bitci kod Munde u provinciji Hispaniji 45. pr. Kr. boreći se uz ostatke pompejevskih snaga.
For even Labienus, one of Caesar's greatest friends, who had been his legate and had fought most zealously with him in all his Gallic wars, now ran away from him and came to Pompey.
