Chinattus taiwanensis is a species of jumping spider (family Salticidae) found exclusively in Taiwan.

[1] This spider has a body length (excluding legs) of 3.9 mm.

The carapace is dark brown, black towards the margins; the legs and the roughly cylindrical abdomen are greyish-black, the latter marked dorsally with four depressions and five pale curved bands and laterally with numerous diagonal black lines.

[2] It can be distinguished from the similar Chinattus validus by the shape of the palps.
