The Three Ducal Ministers (Chinese: 三公; pinyin: Sāngōng), also translated as the Three Dukes, Three Excellencies, or the Three Lords, was the collective name for the three highest officials in Ancient China and Imperial China.

Under this system, the Three Ducal Ministers all held the highest rank of ten-thousand-bushel.
