The Restless Flycatcher, Myiagra inquieta, is a passerine bird in the family Monarchidae.

Also known colloquially as Scissors Grinder, Girl Grinder, or Dishwasher on account of its unusual call, the Restless Flycatcher was first described by ornithologist John Latham in 1802. Its specific epithet is derived from the Latin inquietus 'restless'.

It is found in Australia and Papua New Guinea. It is about 20 cm (8 in) long, with a glossy dark blue crown, a grey back and white underparts. It is similar to the Willie Wagtail, though the lack of a black throat and white eyebrow are distinguishing features. Its main food is insects.

This bird builds a cup-shaped nest from shredded bark and grasses, matted and bound with spider-webbing. Linings used are soft bark, grasses, hair or feathers. It is often decorated with lichen, strips of bark or spiders' egg sacs. The nest site is in the fork of a well-foliaged tree mostly near or overhanging water, though it can be up to twenty or more metres above the ground.
