#### Abstract

We investigate the mean curvature flows in a class of warped products manifolds with closed hypersurfaces fibering over $\mathbb{R}$. In particular, we prove that under some natural conditions on the warping function and Ricci curvature bound for the ambient space, there exists a large class of closed initial hypersurfaces, as geodesic graphs over the totally geodesic hypersurface $N$, such that the mean curvature flow starting from $S_0$ exists for all time and converges to $N$.
