We present a new high-quality nucleon-nucleon potential with explicit charge dependence and charge asymmetry, which we designate Argonne [ital v][sub 18]. The model has a charge-independent part with 14 operator components that is an updated version of the Argonne [ital v][sub 14] potential. Three additional charge-dependent and one charge-asymmetric operators are added, along with a complete electromagnetic interaction. The potential has been fit directly to the Nijmegen [ital pp] and [ital np] scattering database, low-energy [ital nn] scattering parameters, and deuteron binding energy. With 40 adjustable parameters it gives a [chi][sup 2] per datum of 1.09 for 4301 [ital pp] and [ital np] data in the range 0--350 MeV.
