  We investigate Cox rings of minimal resolutions of surface quotient
singularities and provide two descriptions of these rings. The first one is the
equation for the spectrum of a Cox ring, which is a hypersurface in an affine
space. The second is the set of generators of the Cox ring viewed as a subring
of the coordinate ring of a product of a torus and another surface quotient
singularity. In addition, we obtain an explicit description of the minimal
resolution as a divisor in a toric variety.
