Abstract：
In this paper the coherent state which possesses a definite Abelian charge is extended to the case of possessing a definite non-Abelian charge. The SU(3) charged, hypercharged coherent states for both boson and fermion cases are constructed. In this way, the fractionally charged, hypercharged quark states can be obtained naturally. Moreover, this formulation also shows that in order to obtain integrally charged, hyper-charged hadron coherent states, one must introduce color quantum number and proceed the discussion of the SU(6)×SU_c(3) case.
