The Science of Getting Rich is a book written by the New Thought Movement writer Wallace D. Wattles and published in 1910 by the Elizabeth Towne Company. The book is still in print. It was a major inspiration for Rhonda Byrne's bestselling book and film The Secret (2006).

According to USA Today, the text is "divided into 17 short, straight-to-the-point chapters that explain how to overcome mental barriers, and how creation, not competition, is the hidden key to wealth attraction."

The book is included in personal development scholar Tom Butler-Bowdon's list of "50 Success Classics" in his 2004 book of that name.
