Etynodiol, or ethynodiol, is a steroidal progestin of the 19-nortestosterone group which was never marketed.[1][2][3] A diacylated derivative, etynodiol diacetate, is used as a hormonal contraceptive.[1][2] Etynodiol is sometimes used as a synonym for etynodiol diacetate.

It was patented in 1955.[4]
