Thaddeus Ma Daqin (Chinese: 马达钦; born 1968, Shanghai, China) is a Chinese Catholic prelate who served as Bishop of Shanghai from 2014 until 2023.

He was appointed as auxiliary bishop with the approval of the Holy See and Chinese Government in July 2012. Daqin announced his resignation from the Chinese government mandated Catholic Patriotic Association at his episcopal ordination Mass, and was taken into custody as a result. The Chinese Government has detained him under house arrest ever since (largely confined to Sheshan Seminary) and has prevented him from carrying out his episcopal duties.

The Chinese government unilaterally appointed a new bishop of Shanghai in April 2023, which the Vatican approved in July 2023.
