This star system shares the traditional name Albulaan with ν Aquarii. The name derives from an Arabic term al-bulacān (ألبولعان) meaning "the two swallowers". This star, along with ε Aqr (Albali) and ν Aqr (Albulaan), were al Bulaʽ (البلع), the Swallower. In Chinese, 奎宿 (Nǚ Sù), meaning Girl (asterism) (or Woman), refers to an asterism consisting of μ Aquarii, ε Aquarii, 4 Aquarii, 5 Aquarii and 3 Aquarii. Consequently, μ Aquarii itself is known as 女宿二 (Nǚ Sù èr, English: the Second Star of Girl / Woman.)
