托加长袍（拉丁语：Toga，希腊语：τήβεννος，简称托加，或称罗马长袍）是最能体现古罗马男子服饰特点的服装。它是一段呈半圆形长约6米，最宽处约有1.8 米的羊毛制兼具披肩、饰带、围裙作用的服装。穿着时一般在内穿一件麻制的丘尼卡（拉丁语：Tunica），然后将托加搭在左肩并围绕全身。托加也是罗马人的身份象征，只有男子才能穿着，而女子只能穿斯托拉（拉丁语：Stola）及帕拉（拉丁语：Palla），而没有罗马公民权者更是被禁止穿着托加。

The toga, a distinctive garment of Ancient Rome, was a cloth of perhaps 6 metres (20 feet) in length which was wrapped around the body and was generally worn over a tunic. The toga was made of wool, and the tunic under it often was made of linen. After the 2nd century BC, the toga was worn almost exclusively by Roman men. Women were expected to wear the stola, except for women engaged in prostitution, who were required to wear the toga.
