According to Amazon, the popular trilogy has surpassed the seven part epic.
Adds Sara Nelson, the editorial director of books and Kindle at Amazon: "Since debuting in 2008, Katniss Everdeen and the Hunger Games have taken the world by storm, much as Harry Potter did a decade before.
"Interestingly, this series is only three books versus Harry Potter's seven, and to achieve this result in just four years is a great testament to both the popularity of the work and, we think, the growth in reading digitally during that time."
Notably, the major ebook sellers all had large sales on the series, especially when the film was released, leading to a boost in sales.
The Hunger Games were first released in 2008 and the first film based on the book was released earlier this year, bringing in $700 million globally.
