The Xiuguluan River (Chinese: 秀姑巒溪; Hanyu Pinyin: Xiùgūluán Xī; Tongyong Pinyin: Siòuguluán Si; Wade–Giles: Hsiu⁴-ku¹-luan² Hsi¹; Pe̍h-ōe-jī: Siù-ko͘-lôan-khoe) is a river in southeastern Taiwan. It flows through the Huatung Valley for 81 km (50 mi) before emptying into the Pacific Ocean in Fengbin, Hualien.

The river originates on the eastern side of Mabolasi Mountain (on the border with Taitung County) and flows through the Xiuguluan Mountain. It is the largest river in eastern Taiwan. Over 30 species of fish have been found in the river.

The river is known for its many rapids and has become a prime destination for rafting, especially on a 24 km (15 mi) section Rueisuei Bridge to the Changhong Bridge.
