The Institute for New Testament Textual Research (German: Institut für neutestamentliche Textforschung — INTF) at the University of Münster, Westphalia, Germany, is an institute for the investigation of the text of the New Testament. The INTF was founded in Münster in 1959 by Professor Kurt Aland (1915-1994), the first director of the Institute. In 1983 Barbara Aland succeeded her husband, until 2004 when Holger Strutwolf became director of the INTF.
The purpose of founding the Institute was the preparation of an Editio Critica Maior based on the entire tradition of the New Testament in Greek manuscripts, early versions and New Testament quotations in ancient Christian literature. Under Kurt Aland's supervision the INTF collected almost the entire material. The first supplement of the Editio Critica Maior with the General epistles was published in 1997.
The INTF also holds some manuscripts of the New Testament, and took responsibility for registering the New Testament manuscripts, and for editing the Novum Testamentum Graece.
