We calculate the running of the three coupling constants in cosmological, topologically massive 3D gravity. We find that., the dimensionless coefficient of the Chern-Simons term, has a vanishing beta function. The flow of the cosmological constant and Newton's constant depends on., and for any positive. there exist both a trivial and a nontrivial fixed point.
