In order to clarify a pairing symmetry in quasi-one-dimensional organic superconductors (TMTSF)2X, we investigate the superconducting state in the extended Hubbard model on a quarter-filled square lattice within the random phase approximation. We find that a competition among four pairing states including odd-frequency pairing occurs in the quasi-one-dimensional system where the 2kF spin fluctuation coexists with the 2kF charge fluctuation. We suggest that the odd-frequency pairing can appear in a realistic parameter.
