Herein, we describe a new agamid species of the genus Acanthosaura from Central Highlands of Vietnam: Gia Lai Province, Kon Chu Rang NR, and Kon Tum Province: Kon Plông and Ngoc Linh Mountain based on morphological and molecular data. Acanthosaura prasina sp. nov. is distinguished from all congeners by a combination of the following morphological characters. Acanthosaura prasina sp. nov. differs from A. capra, A. murphyi, and A. nataliae by the presence of a short spine on each side of the neck and a smaller body size. From the known species of «lepidogaster» complex and A. coronata it differs in the arrangement of dorsal crests with a distinct double row of vertebral scales, from A. brachypoda in a smaller body size, longer tail and limbs, fewer supra- and infralabials and coloration patterns with a white area on lips and shoulders; from A. lepidogaster by lacking a dark marking on the nape and the absence of a distinct diastema; from A. phongdienensis by lacking a dark marking on the nape. We provide a cyt b-based estimation of diversity of the genus Acanthosaura. A. prasina sp. nov. differs from A. phongdiensis, A. coronata, A. lepidogaster, A. armata, A. crucigera, A. nataliae, A. phuketensis, and Acanthosaura sp. SK in p-distances of 15.4, 24.5, 14.7, 14.6, 16.3, 14.6, 15.4, and 24.4%, respectively. The new species currently known from three localities from Central Highlands was recorded from 800 to 1700 m a.s.l. in the evergreen polydominant forests in the mountainous regions of Gia Lai and Kon Tum provinces. This is the 16th species of Acanthosaura and the ninth species of the genus from Vietnam.
