Brian Marafuji, kilala sa Japan bilang Ryo Marufuji (丸藤亮, Marufuji Ryō), isa siya sa mga fictional character sa anime series na Yu-Gi-Oh! Duel Monsters GX.

Siya ang nakakatandang kapatid ni Paolo Marafuji (Sho Marafuji) at kabilang sa Obelisk Blue kasama sina Alexa Tenjouin (Asuka Tenjouin) at Sean Banzaime (Jun Manjoume). Magkaibigan din sila nina Alexa at ang kapatid niyang si Andrei Tenjouin (Fubuki Tenjouin). Tinagurian siyang Kaiser Brian.
