We present an alternative to Topologically Massive Gravity (TMG) with the same "minimal" bulk properties; i.e. a single local degree of freedom that is realized as a massive graviton in linearization about an anti-de Sitter (AdS) vacuum. However, in contrast to TMG, the new "minimal massive gravity" has both a positive energy graviton and positive central charges for the asymptotic AdS-boundary conformal algebra.
Comment: 21 pages. v2 includes additional references and an extended discussion of the unusual features of the MMG equation. Typos corrected in v3 and a "note added" concerning matter coupling. More sign corrections in v4 plus additional "note added"
