The Kinabalu squirrel (Callosciurus baluensis ) is a species of rodent in the family Sciuridae. It is endemic to highland forest in East Malaysia. Its name is a reference to Mount Kinabalu, though it is not restricted to this mountain. Its tail and upperparts are grizzled blackish, the underparts are reddish-orange, and the flanks have a narrow buff stripe with a broader black stripe below.
