The Discipline of Market Leaders is a 1995 non-fiction book written by Michael Treacy and Fred Wiersema and published by Addison-Wesley.

[2] The core of the book is based on five years of research by the authors into companies such as Wal-Mart, Dell, Southwest Airlines, Cott, Airborne Express, Atlantic Richfield, Home Depot, Intel, and Sony.

[6] Lois Weisberg stated the book "Provides great insight into the linkage of product value, operating excellence and customer focus,"[7] and Dale Dauten from the Chicago Sun-Times also spoke highly of it.

[2] It is alleged the authors spent money on their own book in order to gain the benefits that are common from making The New York Times Best Seller list, such as speaking engagements and consulting opportunities, as well as further book sales, as chart success often begets more chart success.

Treacy was said to be giving around 80 speeches a year, increasing his speaking fee from $25,000 to $30,000 after featuring on the best-seller list.

[10] Following the incident The New York Times improved their methods for filtering bulk sales from affecting the list and made a better effort to hide the names of stores that were reporting for them.
