  We investigate the relationship between mass and spin of quark anti-quark
bound state in non-commutative gauge theory with N=4 supersymmetry. In the
large N and large 't Hooft coupling limit, these bound states correspond to
rotating open strings ending on a D-brane embedded into the supergravity
background dual of the non-commutative field theory. Although the physical
configuration of the open strings are drastically deformed by the
non-commutativity, we find that the relation between the energy and the angular
momentum of the bound state is unaffected by the non-commutativity parameter.
We also clarify the holographic interpretation of quark anti-quark potential in
non-commutative gauge theories.
