The Loyalty Effect is a 1996 book by Fred Reichheld of the consulting firm Bain & Company, and the book's title is also sometimes used to refer to the broader loyalty business model as a whole. Reichheld's book was exceptionally popular with marketing and customer relationship management professionals, and as such the phrase "loyalty effect" has become synonymous in some circles with the more generic concepts covered by the loyalty business model.

In 2001, Reichheld penned a sequel to the book called Loyalty Rules! and released a revised edition of the original work.
