Reimund Bieringer (born 1957) is a German theologian, biblical scholar, Professor Emeritus (with formal duties) of New Testament Exegesis at the Faculty of Theology and Religious Studies, KU Leuven, Belgium, and a Roman Catholic priest of the Diocese of Speyer in Germany. The main areas of his research include the Second Letter to the Corinthians (exegesis and theology), the Gospel of John (Anti-Judaism and the Gospel of John; Mary Magdalene and the Noli me tangere), and biblical hermeneutics (normativity of the future).

Bieringer first studied theology at the Sankt Georgen Graduate School of Philosophy and Theology, and then continued his studies at the Faculty of Theology of the KU Leuven, Belgium, where he defended his doctorate in 1986. His doctoral dissertation presents an exegesis of 2 Corinthians 5:14-21 in its epistolary context and is partially published in Studies on 2 Corinthians.

In 1988 he was ordained a priest in the Roman Catholic Diocese of Speyer, and served in a parish in Rodalben as assistant priest until 1990, when he was appointed as a full-time staff member of the Faculty of Theology (now Faculty of Theology and Religious Studies) at KU Leuven. Between 2008 and 2012 he served as vice-dean for research of that faculty. Since 2014 he has been the coordinator of the Biblical Studies Research Unit. He was also the co-founder and is currently the head of the Faculty's Centre for Women's Studies Theology. He also chairs the Research Group Exegesis, Hermeneutics and Theology of the Corpus Paulinum and Corpus Johanneum. Since 2011, he has been serving as the secretary of the Colloquium Biblicum Lovaniense.

Between 2012 and 2015 Bieringer served as the president of the European Association of Biblical Studies and is currently the president of the Flemish Bible Society. He is also the secretary of Colloquium Oecumenicum Paulinum, and in 2010 served as its president.

The theology and the background of Paul's Second Letter to the Corinthians have belonged to Bieringer's main research interests since the beginning of his academic career. He is known to be one of the long-standing defenders of the letter's unity and integrity.

In his doctoral work, supervised by Jan Lambrecht, and in subsequent publications, he has argued that the genesis of Paul's use of the concept of reconciliation in reference to the divine-human relationship in 2 Cor 5:14-21 is to be sought in Paul's theological reflection on his personal experience of an initial reconciliation with the Corinthians. Bieringer has also suggested that, as opposed to the traditional understanding of καταλλάγητε (katallagēte) in 2 Cor 5:20d as passive, the verb has here a reflexive meaning and thus could be translated as "reconcile yourselves to God" rather than "be reconciled to God".

In a paper presented at the 2008 Society of Biblical Literature Annual Meeting in Boston, Bieringer proposed the term "theology in the making" to refer to the process whereby Paul's everyday life experiences and the resources at his disposal led to the development of Paul's profound theological insights. This paper constituted also an introduction to the series of seminar sessions on Second Corinthians: Pauline Theology in the Making, to take place every year at the Society of Biblical Literature Annual Meetings, from 2008 to 2019.

Some of Bieringer's insights on reconciliation in 2 Corinthians were taken over and developed in a doctoral dissertation by Ivar Vegge, published subsequently in the WUNT series.
