Wanyan Yungong (Chinese: 完顏允恭; 1146－1185), Jurchen name Hutuwa (Chinese: 胡土瓦), was an imperial prince of China's Jurchen-led Jin dynasty.
He was the son of the Emperor Shizong an Empress Mingde.
In the first month of the eighth year of Emperor Shizong's reign, his title was changed back.
In June of the 25th year of Shizong, the prince died of illness in Chenghua Hall.
After hearing the news, Shizong was very sad and accorded him the posthumous name Crown Prince Xuanxiao (宣孝太子).
