In this paper, we study the uniform regularity and vanishing viscosity limit for the compressible nematic liquid crystal flows in three dimensional bounded domain. It is shown that there exists a unique strong solution for the compressible nematic liquid crystal flows with boundary condition in a finite time interval which is independent of the viscosity coefficient. The solutions are uniform bounded in a conormal Sobolev space. Furthermore, we prove that the density and velocity are uniform bounded in W 1,∞ , and the director field is uniform bounded in W 3,∞ respectively. Based on these uniform estimates, one also obtains the convergence rate of the viscous solutions to the inviscid ones with a rate of convergence.
