  We use holography and a string probe approach to compute the drag force on a
quark moving in a thermal plasma of non-commutative Yang-Mills (NCYM) theories
in various dimensions. The gravity background in these cases are described by a
particular decoupling limit of non-extremal (D$(p-2)$, D$p$) brane bound state
system. We show how the drag force on an external quark moving in the dual NCYM
theories gets corrected due to non-commutativity and as a result the effective
viscosity of the plasma gets reduced. We have obtained the drag force for both
small and large non-commutativity. This was known earlier for (3+1)-dimensional
NCYM theory, however, we find that the corrections for the general case
typically depend on the dimensionality of the NCYM theories, indicating that
the structure of the drag force is non-universal.
