Gamma Cephei Ab (disingkat γ Cephei Ab, γ Cep Ab), dinamai secara resmi Tadmor /ˈtædmɔːr/, adalah sebuah eksoplanet berjarak sekitar 45 tahun-cahaya dalam konstelasi Cepheus (sang Raja). Planet tersebut dipastikan berada dalam orbit sekitar Gamma Cephei A pada 2002, tetapi pertama kali diduga ada sekitar 1988 (menjadikan planet tersebut bisa dibilang planet ekstrasurya sejati pertama yang ditemukan).
