Loraine Boettner (/ˈbɛtnər/; March 7, 1901 – January 3, 1990) was an American theologian, teacher, and author in the Reformed tradition.

His father, William Boettner, was a Christian school superintendent and had been born in Schwartzenhazel, Germany.

Upon his wife's death, in 1958, Boettner returned to his home state, settling in Rock Port, Missouri, where he remained the rest of his life.

[5] A recent doctoral study (Catholic) claims that the research done by Boettner in Roman Catholicism "is simply flimsy" and makes use of old and refuted anti-Catholic clichés.

[6] The Reformed Doctrine of Predestination and Immortality was translated into Chinese by Charles H. Chao (1952, 1962), into German by Ivo Carobbio, and into Japanese.
