Salix kusanoi is a species of willow in the family Salicaceae. It is endemic to Taiwan. It is threatened by habitat loss.
It is a deciduous tree growing to 7m (23feet) tall. The leaves are alternate, 9 cm long and 4 cm broad, with finely serrated edge and glands. Both sides of the leaves are green and have dark orange fine hairs. The hairs on the underside of the leaves are more obvious, and the hairs can be easily wiped off.
