Mu Arae (μ Ara, μ Arae), yang disebut dalam katalog Henry Draper HD 160691, adalah sebuah bintang berjenis G sekuensi utama yang berjarak 50 tahun cahaya jauhnya dari Bumi di konstelasi Ara. Bintang tersebut memiliki sebuah sistem planetarium dengan empat planet yang diketahui, tiga diantaranya memiliki massa yang sama dengan Jupiter. Planet yang paling dalam di sistem tersebut adalah "Neptunus panas atau Bumi super" pertama yang ditemukan.
