Dimethyldienolone (developmental code name RU-2788), or 7α,17α-dimethyldienolone, also known as δ⁹-7α,17α-dimethyl-19-nortestosterone or as 7α,17α-dimethylestr-4,9-dien-17β-ol-3-one, is a 17α-alkylated androgen/anabolic steroid of the 19-nortestosterone group which was never marketed. It is closely related to dimethyltrienolone, as well as to mibolerone and metribolone. Dimethyldienolone shows high affinity for the androgen and progesterone receptors.

Dimethyldienolone is made from almestrone.
