罗慕路斯（Romulus，约前771年出生，约前717年7月5日逝世）与瑞摩斯（Remus，约前771年出生，约前753年4月21日逝世）是罗马神话中罗马市的奠基人。在罗马神话中他们是一对双生子。他们的母亲是女祭司雷亚·西尔维亚，他们的父亲是战神玛尔斯。按照普鲁塔克和蒂托·李维等的传统罗马历史记载罗穆卢斯是罗马王政时代的首位国王。

兄弟俩人后来因为就谁获得当地神的支持应该给新建的城市命名的问题而发生争执，甚至爆发战斗，结果罗穆卢斯将瑞摩斯杀死。此后罗穆卢斯还创立了罗马军团和罗马元老院。通过抢劫附近的萨宾人的妇女他为新建的城市增加了人口，由此将罗马人与萨宾人融合为一个民族。罗穆卢斯成为古罗马最大的征服者，将大量地区及其居民纳入罗马的统治范围。

Romulus /ˈrɒmjᵿləs/ and Remus /ˈriːməs/ were the twin brothers and main characters of Rome's foundation myth. (The pronunciation in English is different from the Latin original Rōmulus and Rĕmus). According to Roman tradition, of which Livy's account is now the earliest to survive in full, their mother was Rhea Silvia, daughter of Numitor, king of Alba Longa. Before their conception, Numitor's brother Amulius seized power, killed Numitor's male heirs and forced Rhea Silvia to become a Vestal Virgin, sworn to chastity. Rhea Silvia conceived the twins by the god Mars. Once the twins were born, Amulius had them abandoned to die in the Tiber river. They were saved by a series of miraculous interventions: the river carried them to safety, a she-wolf found and suckled them, and a woodpecker fed them. A shepherd and his wife found them and fostered them to manhood as simple shepherds. The twins, still ignorant of their true origins, proved to be natural leaders. Each acquired many followers. When they discovered the truth of their birth, they killed Amulius and restored Numitor to his throne. Rather than wait to inherit Alba Longa, they chose to found a new city.
