The Nilgiri striped squirrel (Funambulus sublineatus) is a threatened species of rodent, a small squirrel (Sciuridae) from rainforests in the southern Western Ghats, including the Nilgiris, in Peninsular India. It formerly included Funambulus obscurus from Sri Lanka as a subspecies, at which point the English name of the combined species also was dusky striped squirrel (a name now restricted to the Sri Lankan species).
