The Kalkadoon grasswren (Amytornis ballarae), also called the Ballara grasswren, is a species of passerine bird in the family Maluridae. It is endemic to Australia.
It is similar to the dusky grasswren, though the markings are generally brighter and more defined, e.g. the wing coverts and remiges are grayish with a small rufous patch at the base of the outer remiges, compared with the same parts of the dusky grasswren being a uniformly dull rufous-brown.
