The Samoan island thrush (Turdus samoensis) is a species of passerine bird in the thrush family Turdidae.

It was formerly considered a subspecies of the island thrush, but in 2024 the island thrush complex was split into 17 different species by the IOC and Clements checklist based on morphological and phylogenic differences.

[1][2] The Samoan island thrush was first described by clergyman and zoological collector Henry Baker Tristram in 1879 as Turdus samoensis.

[3] For a long time afterwards it was considered a subspecies of island thrush.

However following a phylogenetic study in 2023, and with consideration to morphological differences between subspecies, the Samoan island thrush is now treated as a distinct species.
