Berberidopsidaceae is a family of flowering plants. Such a family has been recognized by only a few taxonomists: the plants involved have often been treated as belonging to family Flacourtiaceae. The APG II system, of 2003 (unchanged from the APG system, of 1998), does recognize this family, unplaced as to order and merely assigned to the clade core eudicots. The family consists of one or two genera, Berberidopsis, with two species (B. beckleri and B. corallina) and Streptothamnus, with a single species (S. moorei).
