In this paper, we define Clairaut semi-invariant Riemannian map F from a Riemannian manifold (M, g M ) to a Kähler manifold (N, g N , P ) with a non-trivial example. We find necessary and sufficient conditions for a curve on the base manifold of semi-invariant Riemannian map to be geodesic. Further, we obtain necessary and sufficient conditions for a semi-invariant Riemannian map to be Clairaut semi-invariant Riemannian map. Moreover, we find necessary and sufficient condition for Clairaut semi-invariant Riemannian map to be totally geodesic. In addition, we find necessary and sufficient condition for the distributions D1 and D2 of (kerF * ) ⊥ (which are arisen from the definition of Clairaut semi-invariant Riemannian map) to define totally geodesic foliation. Finally, we obtain necessary and sufficient conditions for (kerF * ) ⊥ and base manifold to be locally product manifold D1 × D2 and N (rangeF * ) × N (rangeF * ) ⊥ , respectively.
