Stephen (often rendered as Latin Stephanus) Kim Sou-hwan (Korean: 김수환; Hanja: 金壽煥; May 8, 1922 – February 16, 2009) was a cardinal of the Roman Catholic Church and the former archbishop of Seoul, South Korea.

After serving briefly as a parish priest in Andong and then as a secretary in the Archdiocese of Daegu, he traveled to Germany to study sociology at Münster University from 1956 to 1963.

Kim was raised to the rank of cardinal-priest of San Felice da Cantalice a Centocelle by Pope Paul VI in the consistory of April 28, 1969, having become the archbishop of Seoul in 1968 after being the bishop of Masan since 1966.

During Park Chung Hee and his successor's military dictatorship of the '70s and the '80s, the Korean Catholic Church under Kim's leadership was highlighted as a focal point of South Korea's democratization movement.

In 1998, Cardinal Kim retired as the archbishop of Seoul, shortly after serving as president-delegate of the Special Assembly for Asia of the World Synod of Bishops.
