The white-footed dunnart (Sminthopsis leucopus) is a marsupial that occurs on Tasmania and mainland Australia.

In southern New South Wales, the white-footed dunnart is known to occur at elevations at least as high as 1000 metres.

The female white-footed dunnart will give birth in September or October, and up to ten joeys may be delivered.

After eight weeks old, the young will exit their mothers pouch, continue nursing for a month, then disperse.

An unnamed subspecies of white-footed dunnart was recently found in northern Queensland.
