The name Tadiva (Tadiua) appears in a single Spanish document written late in the seventeenth century. As it occurs in a list of twenty-one tribes, nineteen of which are clearly Caddoan, it seems likely that Tadiva refers to a small and perhaps peripheral tribe of the southwestern or Hasinai division of Caddo Indians in eastern Texas.
