Any of a group of extinct flightless kiwi-like birds that lived in New Zealand. There were 19 species; they varied from 0.5 to 3.5 m/2 to 12 ft, with strong limbs, a long neck, and no wings. The largest species was Dinornis maximus. The last moa was killed in the 1800s. (Order Dinornithiformes.)

The Maori used them as food, and with the use of European firearms killed them in excessive numbers.
