Yes. The most famous and well-studied are the Iroquois (although the word 'matriarchal' is controversial, they were matrilineal in major property distribution and mothers had executive veto power over major decisions of men's counsels, creating a kind of bicameral system).

See Judith Brown's "Iroquois Women" (which is reprinted in many places).

Many Native American cultures favored a kind of division of labor between the sexes that awarded major decision making to each sex/gender. So they wouldn't be called either patriarchal or matriarchal. There are, imo, no "matriarchal" societies in which women possess the kind of power that men do in the patriarchal societies.
