Hans Küng (born March 19, 1928, in Sursee, Canton of Lucerne) is a Swiss Catholic priest, theologian, and prolific author. Since 1995 he has been President of the Foundation for a Global Ethic (Stiftung Weltethos). Küng is "a Catholic priest in good standing", but the Vatican has rescinded his authority to teach Catholic theology. He had to leave the Catholic faculty, but remained at the University of Tübingen as a professor of ecumenical theology, serving as an emeritus professor since 1996. Although Küng is not officially allowed to teach Catholic theology, neither his bishop nor the Holy See have revoked his priestly faculties.

Küng studied theology and philosophy at the Pontifical Gregorian University in Rome and was ordained in 1954. He continued his education in various European cities, including the Sorbonne.

In 1960, he was appointed professor of theology at Eberhard Karls University, Tübingen, Germany. Like his colleague Joseph Ratzinger (now Pope Benedict XVI), in 1962 he was appointed peritus by Pope John XXIII, serving as an expert theological advisor to members of the Second Vatican Council until its conclusion in 1965. At Küng's instigation, the Catholic faculty at Tübingen appointed Ratzinger as professor of dogmatics. However, due to the 1968 students revolt, Ratzinger moved to the University of Regensburg, ending cooperation between the two.
