  We study representations of the Poincar\'e group that have a privileged
transformation law along a p-dimensional hyperplane, and uncover their
associated spinor helicity variables in D spacetime dimensions. Our novel
representations generalize the recently introduced celestial states and
transform as conformal primaries of SO(p,1), the symmetry group of the
p-hyperplane. We will refer to our generalized states as ``partially
celestial." Following Wigner's method, we find the induced representations,
including spin degrees of freedom. Defining generalized spinor helicity
variables for every D and p, we are able to construct the little group
covariant part of partially celestial amplitudes. Finally, we briefly examine
the application of the pairwise little group to partially celestial states with
mutually non-local charges.
