Liu You (simplified Chinese: 刘友; traditional Chinese: 劉友; pinyin: Liǘ Yǒu, died 181 BC) was the sixth son of Emperor Gaozu of Han. He was made Prince of Huaiyang in 196 BC, and recreated as Prince Ji of Zhao two years later. You married Empress Dowager Lü's niece and was found to be having affairs with secret mistress. Empress Dowager Lü summoned him to the capital and imprisoned him there without food. While in prison, You made a song cursing the deeds which Empress Dowager Lü had done to the Liu family. He was afraid to commit suicide and ended up starving to death.
