- (Roman mythology) The legendary founder of Rome and the twin brother of Romulus.
- A male given name, rare in English.
Remus's name may have originally meant "twin," from Old Latin *Yemos, *Yemonos (“twin”), from Proto-Italic *jemnos (“paired”), from Proto-Indo-European *yemH-no- (“connected, paired”), from *yemH-. Cognate with Old Norse Ýmir, Sanskrit यम (yama, “twin-born”). The initial 'R' was probably introduced to make the name sound more like Romulus.
