Four-dimensional N=2* super Yang-Mills theory is obtained by introducing a one parameter mass deformation to one of the hypermultiplets of four-dimensional 
N=4 Yang-Mills. Four- dimensional N=2* Yang-Mills is a non-conformal gauge theory and its gravitational dual has been constructed by Pilch and Warner. The 
theory exhibits many interesting properties at finite temperature. We formulate N=2* 
super Yang-Mills on a Euclidean spacetime lattice using the method of topological twisting. The lattice formulation is local, gauge invariant, doubler free 
and preserves one supersymmetry charge at finite lattice spacing. Such a construction can be used for finite temperature nonperturbative explorations of the theory and
validate the gauge-gravity duality conjecture in a non-conformal theory.
