The Sundaic island thrush (Turdus javanicus), also known as the Sunda island thrush,[1] is a species of passerine in the family Turdidae.

It has the largest distribution in the island thrush complex, ranging from northern Sumatra south to Java, with a disjunct population in northern Borneo.

The Sundaic island thrush's nominate subspecies, T. j. javanicus was first described in 1821 by American naturalist Thomas Horsfield as Turdus javanicus.

[1] It was later considered to be a subspecies of Island thrush.

In 2024, following a phylogenic study of Island thrush subspecies in 2023, the Island thrush was split into 17 different species by the IOC and Clements checklist.
