Agama Ryukyu, Ryukyu Shinto (琉球神道), Nirai Kanai Shinkou (ニライカナイ信仰), atau Utaki Shinkou (御嶽信仰) merupakan sistem kepercayaan masyarakat asli Kepulauan Ryukyu. Walaupun legenda dan tradisi tertentu yang berbeza dari tempat ke tempat dan pulau ke pulau, agama Ryukyu secara umumnya bercirikan penyembahan nenek moyang (lebih tepat memberi :penghormatan kepada nenek moyang") dan menghormati hubungan antara yang hidup, mati, dewa dan semangat alam semula jadi. Sebahagian daripada kepercayaannya, seperti yang berkaitan dengan semangat genius loci dan makhluk lain yang diklasifikasikan antara dewa-dewa dan manusia, menandakan akar animistik purba, seperti kebimbangannya terhadap mabui(まぶい?), atau intipati hidup.
Lama kelamaan, agama Ryukyu telah dipengaruhi dengan agama China (Taoisme, Konfusianisme, and kepercayaan rakyat), Buddhisme dan Shinto.[1] Salah satu kepercayaan kuno ialah kepercayaan onarigami (おなり神), keunggulan semangat wanita yang datang dari Amamikyu, yang membenarkan pembinaan sistem noro.
