  We perform a holographic renormalization of gravity duals to little string
theories. In particular, we construct counterterms which yield a well-defined
type II action for NS-sector linear dilaton backgrounds. Our methods are based
on a similar recent construction in asymptotically flat spacetimes, and our
work demonstrates in detail the parallels between asymptotically flat and
linear dilaton boundary conditions. The counterterms guarantee that (i) the
on-shell action is finite and (ii) asymptotically linear dilaton solutions are
stationary points of the action under all boundary condition preserving
variations. We use the resulting action to compute a boundary stress tensor and
the associated conserved charges.
