Abstract
For a compact manifold M and a differentiable stack 
presented by a Lie groupoid X, we show the Hom-stack 
is presented by a Fréchet–Lie groupoid Map(M, X) and so is an infinite-dimensional differentiable stack. We further show that if 
is an orbifold, presented by a proper étale Lie groupoid, then Map(M, X) is proper étale and so presents an infinite-dimensional orbifold.
