  In this article, we introduce Clairaut anti-invariant Riemannian maps from
Riemannian manifolds to trans-Sasakian manifolds. We derive necessary and
sufficient condition for an anti-invariant map to be Clairaut when base
manifold is trans-Sasakian manifold. We discuss the integrability of range\pi_*
and (range\pi_*)^\perp. Further, we establish harmonicity of these maps.
Finally, we construct nontrivial examples of such maps for justification.
