Daftar spesies mamalia di Jepang

Ini adalah daftar **spesies mamalia** yang tercatat di **Jepang** (tidak termasuk populasi peliharaan dan penangkaran ). Dari 172  spesies mamalia yang ditemukan—112 mamalia darat asli (yang endemik diidentifikasi di bawah; jumlah ini mencakup 37 spesies kelelawar), 19 spesies yang diperkenalkan, 40 spesies Setasea, dan duyung —161 terdaftar untuk wilayah Jepang pada Daftar Merah Spesies yang Terancam IUCN : dari jumlah tersebut, tiga taksa terancam punah secara kritis ( tikus-duri muennink, lasiwen yanbaru, dan pungit kelam ), dua puluh dua terancam punah, delapan rentan, dan sebelas hampir terancam ; singa laut Jepang dan sekiwen sturdee dievaluasi sebagai punah . Meskipun pada tingkat global serigala kelabu dinilai sebagai spesies yang paling tidak perlu dikhawatirkan, dua subspesies Jepang, serigala Hokkaido dan serigala Jepang, juga mengalami kepunahan baru-baru ini; Daftar Merah Kementerian Lingkungan Hidup Jepang tahun 2020 juga mencantumkan kalong okinawa dan berang-berang sungai jepang sebagai spesies yang punah, serta subspesies prok-bruk kecil miyako .  

Hingga Januari 2023, demi perlindungan mereka, lima belas spesies dan subspesies telah ditetapkan sebagai spesies terancam punah nasional berdasarkan perintah kabinet sesuai dengan Undang-Undang Konservasi Spesies Flora dan Fauna Liar yang Terancam Punah tahun 1992.
