    Opsin adalah protein transmembran yang sensitif terhadap cahaya, yang terikat pada aldehida vitamin A. Secara umum ada dua jenis protein yang disebut opsin. Keduanya memiliki bentuk dan fungsi yang sama.
    Opsin jenis pertama terdapat pada prokariota, sedangkan binatang biasanya memiliki opsin jenis kedua. Sampai sekarang belum ditemukan ada opsin di luar kedua kelompok tadi (misalnya pada tanaman, jamur, dan lain-lain) walaupun ada yang telah melaporkan menemukan opsin pada porifera namun penemuan ini belum dikonfirmasi.
