Abstract: Three new species of the genus Niitakacris Tinkham, 1936 from Taiwan, China are described in the present paper, including N. arishanensis sp. nov., N. xiai sp. nov. and N. taiwanensis sp. nov. N. arishanensis sp. nov. differs from all known species of the genus by the hind femur not red on inner side and maximum width of basal part 4 times width of apical part in cercus of male. N. xiai sp. nov. is similar to N. rosaceanum (Shiraki, 1910) and Niitakacris taiwanensis  sp. nov., but differs from the two species by the length of interspace of mesosternum longer than minimum width and tegmina not reaching the hind margin of first abdominal tergite. N. taiwanensis sp. nov. is similar to N. rosaceanum (Shiraki, 1910), but differs from the latter by eye smaller, vertical diameter 1.4 times subocular furrow; furculae separated; longitudinal groove at base of epiproct shorter, not reaching to the middle, apex rounded. A key to all five species of the genus from Taiwan is given. Type specimens are deposited in the National Museum of Natural Science, Taichung, Taiwan, China and the Institute of  Entomology, Taiwan University, Taibei, Taiwan, China respectively.
