Ray Sherwin, born in 1952 in Yorkshire, England, is an English occult author and publisher. Together with Peter J. Carroll, he is one of the originators of the system of magical discipline called chaos magic.
In the late 1970s, he began publishing a magazine called The New Equinox, an irregular journal dealing with Thelemic magick, chaos magic and related subjects. He developed chaos magic theory and early rituals.
In 1978, he co-founded the Illuminates of Thanateros with Carroll, later publishing Carroll’s book, Liber Null. Also during 1978, Sherwin wrote and published The Book of Results. These two books, Liber Null and The Book of Results, were the first books written on the topic of chaos magic.
He is also the author of the magical texts The Theatre of Magick and Strange Smell in the Car.
