The Wallacean island thrush (Turdus schlegelii), also known as the Sulawesi island thrush,[1] is a species of passerine in the family Turdidae.

It was formerly considered to be multiple subspecies of the island thrush, but was classified as a distinct species in 2024 by the IOC and Clements checklist based on morphological and phylogenic evidence.

[2][3] The Wallacean island thrush was first described by ornithologist Philip Sclater in 1861 as Turdus schlegelii based on specimens collected from Timor.

[1] It's binomial name, T. scheleglii was in honour of fellow ornithologist Hermann Schlegel.

Following a 2023 phylogenic study of the island thrush complex, and with consideration given to morphological differences, the island thrush was split into 17 species in 2024, including the Wallacean island thrush.
