Yue, also known as Yuyue (于越), was a state in ancient China which existed during the first millennium BC – the Spring and Autumn and Warring States periods of China's Zhou dynasty – in the modern provinces of Zhejiang, Shanghai and Jiangsu. Its original capital was Kuaiji ; after its conquest of Wu, Yue relocated its court north to the city of Wu. Yue was conquered by Chu in 306 BC.

The Spring and Autumn period in Chinese history lasted approximately from 770 to 481 BCE which corresponds roughly to the first half of the Eastern Zhou period. The period's name derives from the Spring and Autumn Annals, a chronicle of the state of Lu between 722 and 481 BCE, which tradition associates with Confucius. During this period, royal control over the various local polities eroded as regional lords increasingly exercised political autonomy, negotiating their own alliances, waging wars amongst themselves, up to defying the king's court in Luoyi. The gradual Partition of Jin, one of the most powerful states, is generally considered to mark the end of the Spring and Autumn period and the beginning of the Warring States period.
