The white-bellied whipbird (Psophodes leucogaster), also called the Mallee whipbird, is a species of bird in the family Psophodidae.

It had not been seen or heard in Victoria for 40 years until 2022 when a recording of its song was made in Big Desert Wilderness Park.

[1] The species was formerly considered as a subspecies of Psophodes nigrogularis, so shared the common name of "western whipbird".

The Clements Checklist refers to this species with the common name western whipbird (white-bellied) to distinguish it from P. nigrogularis (black-throated).

[2] The white-bellied whipbird was described by the Australian ornithologists Frank Howe and John Ross in 1933.
