The Border or Upper Tami languages are an independent family of Papuan languages in Malcolm Ross's version of the Trans–New Guinea proposal.
Unlike the neighboring Sepik languages and many other Papuan language families of northern New Guinea, Border languages do not have grammatical gender or number (dual and plural forms).
