Li Xin (Chinese: 李歆; died 420), courtesy name Shiye (士業), nickname Tongzhui (桐椎), was a duke of the Chinese Western Liang dynasty during the Sixteen Kingdoms period. He succeeded his father Li Gao (Prince Wuzhao) in 417 and aggressively tried to pursue campaigns against rival Northern Liang's prince Juqu Mengxun, but fell into a trap set by Juqu Mengxun in 420 and was killed in battle, bringing destruction to his state (although his brother Li Xun tried to hold out but was defeated soon as well).
