  Quoric manifolds are the quaternionic analogue of toric manifolds. They admit
a locally nice action of $(S^3)^n$ and the quotient is a manifold with corners.
We show that they satisfy equivariant rigidity. More precisely, any locally
linear $(S^3)^n$-manifold that it is equivariantly homotopic equivalent to a
quoric manifold is equivariantly homeomorphic to it. The proof is given by
generalising the methods of used in Coxeter and toric manifolds.
