Mayacaceae is the botanical name for a family of flowering plants. Such a family has not been recognized by all that many taxonomists.

The APG II system, of 2003, does recognize such a family, and assigns it to the order Poales in the clade commelinids, in the monocots. The family consists of probably less than a dozen species, in one genus, Mayaca.

This represents a slight change from the APG system, 1998, which left the family unplaced as to an order, but did place it in this same clade (although it used the spelling "commelinoids").
