In this paper, we consider the regularity criterion for 3D incompressible Navier-Stokes equations in terms of one directional derivative of the velocity in anisotropic Lebesgue spaces. More precisely, it is proved that u becomes a regular solution if the 3u satisfies0T3u(t)Lx1pLx2qLx3rβ1+ln(3u(t)L2+e)dt<, where 2β+1p+1q+1r=1 and 2<p,q,r,1(1p+1q+1r)0.
