Eastern Tasmanian is an aboriginal language family of Tasmania in the reconstruction of Claire Bowern.

Bayesian phylogenetic analysis suggests that four (at p < 0.20) to five (at p < 0.15) Eastern Tasmanian languages are recorded in the 26 unmixed Tasmanian word lists (out of 35 lists known). These cannot be shown to be related to other Tasmanian languages based on existing evidence. The languages are:

Two of the lists reported to be from Oyster Bay contain substantial Northeastern admixture (see Northeastern Tasmanian languages), which Bowern believes to be responsible for several classifications linking the languages of the east coast. However, once that admixture is accounted for, the apparent links disappear.
