Munditia tasmanica, common name the Tasmanian liotia, is a species of small sea snail, a marine gastropod mollusk, in the family Liotiidae.

The small, sordidly white shell has a discoid shape.

The spire is plano-depressed, ornamented thickly with spiral sub-obsolete ribs and longitudinal lirae, with two nodose keels at the periphery.

The nodes on the upper carina become little raised hollow rounded squamae on the second whorl.
