Eight Lectures on Yoga is a book by English occultist and teacher Aleister Crowley about the practice of Yoga. The book is number four of volume three of The Equinox, which was published by the Ordo Templi Orientis. The work is largely a demystified look at Yoga, using little to no jargon or satirical humor. It is divided under two sections into eight parts, which are transcripts of eight one-hour lectures on the subject given by Crowley.

Eight Lectures on Yoga is divided into two sections: "Yoga for Yahoos" and "Yoga for Yellowbellies". In the book, Crowley instructs students on the steps needed to approach mysticism through Yoga, and details the complications that arise along the path. One intent Crowley had in writing the book was to dispel the various myths surrounding Yoga in Europe at the time - most thought it to be an exotic, Eastern ritual of the ancient past.
