Augustine Hu Daguo (15 May 1921 – 17 February 2011) was the underground Roman Catholic bishop (as such, he was then considered a part of the Vatican-recognized hierarchy in China approved by and in communion with the Pope) of the Apostolic Prefecture of Shiqian, Shiqian (Shihtsien), Guizhou, China.
Augustine Hu Daguo was born on 15 May 1921 to a family of long Christian tradition in Tongzhou, Pingtang, Guizhou.
In 1936 he entered the Minor Seminary of the Roman Catholic Archdiocese of Guiyang based in the capital city of Guizhou Province.
After his presbyteral ordination, he taught in the Major Seminary, and in 1955 he was sent to work in the parish of Youtangkou as the pastoral vicar.
Four years later he was removed from his position, and returned to Guizhou Province, where he was appointed pastor of Duyun, Dushan, Fuquan, Tuanbo, and Wen'an.
