The Science of Getting Rich is a self-help book written by American new thought writer Wallace D. Wattles, one of the widely quoted author whose other works include The Science of Being Well, The Science of Being Great, and How to Get What You Want.

This book is pragmatical, not philosophical; a practical manual, not a treatise upon theories. It is intended for the men and women whose most pressing need is for money; who wish to get rich first, and philosophize afterward. It is for those who have, so far, found neither the time, the means, nor the opportunity to go deeply into the study of metaphysics, but who want results and who are willing to take the conclusions of science as a basis for action, without going into all the processes by which those conclusions were reached.
