Tjaernoeia is a genus of sea snails, marine gastropod mollusks in the informal group Lower Heterobranchia.[3] They are named after the marine laboratory at Tjärnö, Strömstad, Sweden. Their shells are rounded, thin and translucent.

There are four species of Tjaernoeia. Two of them are found in the Bohuslän region of Sweden: Tjaernoeia exquisita and Tjaernoeia unisulcata.[4] Tjaernoeia boucheti can be found in Scandinavia and in Iceland. Tjaernoeia michaeli has been found in Antarctica and Brazil.[5]

Tjaernoeia is the only genus in the family Tjaernoeiidae.[6] Their closest relatives are Parvaplustridae.[7]
