Aloysius Chen Guodi (; 7 November 1875 - 9 March 1930) was a Chinese Catholic priest and Bishop of the Roman Catholic Diocese of Fenyang from 1926 to 1930 until his death.
Chen was born in Anyangcun, Shanxi in 1875. He entered the Franciscans in 1896 in a village named Dong'ergou (). He was ordained a priest on March 13, 1903.
After the Boxer Rebellion, Chen was tasked with investigating the situation of Catholics in Shanxi.
In Shanxi, Chen worked as secretary to two Italian bishops and taught in Taiyun seminary. In addition, he led a Catholic middle school in the city. This was the only Catholic middle school in Shanxi at that time. He was appointed apostolic vicar by Fenyang on May 10, 1926, and was consecrated by Pope Pius XI on October 28, 1926. When Chen and five other Chinese priests (Philippus Zhao Huaiyi, Simon Zhu Kaimin, Odoric Cheng Hede, Melchior Sun De-zhen, and Joseph Hu Ruoshan) were consecrated in Rome, they became the first Chinese Catholic Bishops in modern times.
As a bishop, he was the apostolic vicar of Fenyang and focused on developing vocations to the priesthood from Chinese.
He died in 1930.
