Beta Monocerotis (Beta Mon, β Monocerotis, β Mon) merupakan sebuah sistem tiga bintang di rasi Monoceros.^[1] Diamati dengan mata telanjang, bintang ini nampak sebagai buintang tunggal dengan magnitudo semu 3,74, sehingga merupakan bintang paling terang di rasi Monoceros.^[2] Pengamatan melalui teleskop menunjukkan tiga bintang. Sistem bintang ini terdiri dari tiga bintang Be, β Monocerotis A, β Monocerotis B, dan β Monocerotis C. Terdapat juga sebuah bintang dekat yang kemungkinan tidak terikat secara fisik dengan tiga bintang lainnya.^[1]

Beta Monocerotis A

Beta Monocerotis A (Beta Mon A, β Monocerotis A, β Mon A) merupakan bintang Be dengan massa sekitar 7 massa Matahari dan luminositas of 3200 kali Matahari.^[1]

Beta Monocerotis B

Beta Monocerotis B (Beta Mon B / β Monocerotis B / β Mon B) merupakan bintang Be dengan massa sekitar 6,2 massa Matahari dan luminositas 1600 kali Matahari.^[1]

Beta Monocerotis C

Beta Monocerotis C (Beta Mon C / β Monocerotis C / β Mon C) merupakan bintang Be dengan massa sekitar 6 massa Matahari dan luminositas 1300 kali Matahari.^[1] Bintang ini diperkirakan merupakan bintang ganda melalui pengamatan interferometrik pada tahun 1988, namun hingga sekarang belum dapat dikonfirmasi.^[12]^[13]
