Wang Hong (王弘) (379–432), courtesy name Xiuyuan (休元), formally Duke Wenzhao of Huarong (華容文昭公), was a high-level official of the Chinese Liu Song dynasty.
Wang became the governor of the strategically important Pengcheng Commandery (彭城, roughly modern Xuzhou, Jiangsu) instead.
Wang briefly visited the capital Jiankang in 422, but then was returned to his post at Jiang Province, and he was not one of the officials whom Emperor Wu entrusted his son and crown prince Liu Yifu to before he died later that year, and Wang did not appear to have increased authority after Liu Yifu took the throne as Emperor Shao.
Before Emperor Shao could get up from bed in the morning, the soldiers were already in his bedchamber, and he made a futile attempt to resist, but was captured.
Emperor Wen did not accept his resignation but did transfer some of Wang Hong's responsibilities to Liu Yikang.
However, Liu Yikang later grew increasingly impatient, complaining in particular that Wang Hong was frequently ill and cannot govern from his sickbed.
Consistent with what he did with his father's promissory notes, Wang left his household with relatively little property, and upon hearing this, Emperor Wen awarded his family a large grant.
