گیرنده بتای رتینوئیک اسید (انگلیسی: Retinoic acid receptor beta) یا به اختصار RAR-beta، یک پروتئین است که در انسان توسط ژن «RARB» کُدگذاری میشود.[۴][۵]
این پروتئین، یک گیرنده هستهای، و یکی از انواع گیرندههای رتینوئیک اسید است و نخستین بار، در سرطان کبد (از نوعِ هپاتوسلولار) کشف شد.
اختلال در این ژن همچنین، در ضایعات پیشسرطانی سرطان دهانه رحم[۶] و نیز در سرطان مهبل ناشی از لیکن اسکلروز مهبل[۷] مشاهده شدهاست.
