Jay Joseph Wiseman (born 1949) is an American BDSM author, educator, and expert legal witness. His most famous work is the book SM 101: A Realistic Introduction, which has somewhere in the area of 100,000 copies in print. It is also one of the Society of Janus' "Suggested Readings" regarding BDSM.

It goes by many names: bondage and discipline, dominance and submission, sadomasochism, and more. In Jay Wiseman's SM 101, the long-taboo subject of consensual sadomasochism is accurately, insightful presented in the context of adult human sexuality, experience and tradition for the interested non-specialist general reader. SM 101 surveys the entire spectrum of consensual sadomasochistic practices from from bondage, to spanking, to erotic role-playing, and more. Now in an expanded second edition, SM 101 includes a new chapter on starting and running sadomaschistic organizations and events for consenting adults.
