Sun Deng (209–241), style name Zigao, was a crown prince of the state of Eastern Wu during the Three Kingdoms period. He was the eldest son of Sun Quan, the founding emperor of Wu. It is known that Sun Deng was both wise and virtuous, having all the makings of a great man. He studied the Classic of Changes, and was a poet and a musician. However, Sun Deng was destined never to succeed his father because he died from illness at a relatively young age of 31. Sun Deng married Zhou Yu's daughter and they had three children: Sun Fan, Sun Ying, and Sun Xi. He was posthumously honoured as "Crown Prince Xuan".
