New England Institute of Religious Research (NEIRR) is a countercult ministry located in Massachusetts which provides information on groups which it considers to be cults.

New England Institute of Religious Research was co-founded by George Mather, coauthor of Dictionary of Cults, Sects, Religions and the Occult,[2][3] along with Robert Pardon.

[5] Attleboro District Court Judge Kenneth Nasif appointed Pardon to serve as guardian ad litem for the children that were previously removed from the group.

[17][18] In his capacity as director of the New England Institute of Religious Research, Pardon presented at a conference of the International Cultic Studies Association in 2001,[19] and again in 2003[20] and 2004.

[21] The Institute is referenced as a resource for information on religious groups, in books including The Cult Next Door,[22] Reflected Truth,[23] Twisted Scriptures,[24] and When Prayer Fails.

[9] In 1999, the New England Institute of Religious Research purchased a nursing home in Lakeville, Massachusetts, intended to serve as a treatment center for up to 25 former members of cults.

[31] The Morning Call quoted a director of the Institute, George Mather, as instructing community residents that Satanists perform rituals during Halloween to summon demons.
