Fantasy is the genre that dreams big. It builds worlds with intricate magic systems, populates them with mythical creatures, and spins tales that span decades. That's why some of the most unforgettable book trilogies in history belong to fantasy. Whether you're into YA adventures like His Dark Materials or grimdark sagas like The Broken Empire, there's a trilogy for every taste. Here are the greatest fantasy trilogies of all time, ranked.
8. The Broken Empire Trilogy
Mark Lawrence's Broken Empire trilogy is a dark fantasy masterpiece. It follows Prince Jorg Ancrath, a ruthless teenager who abandons his royal birthright to lead a band of outlaws on a quest for the throne. Set in a post-apocalyptic Europe, the series blends medieval fantasy with remnants of forgotten technology. The trilogy includes Prince of Thorns, King of Thorns, and Emperor of Thorns. Lawrence's non-linear storytelling and moral ambiguity make this a must-read for fans of dark fantasy.
7. Phèdre's Trilogy
Jacqueline Carey's Kushiel's Legacy series broke new ground with its sex-positive, politically nuanced fantasy. The Phèdre trilogy—Kushiel's Dart, Kushiel's Chosen, and Kushiel's Avatar—is a landmark in queer representation and BDSM themes. It's a thrilling blend of alternate history, espionage, and high-stakes battles that will appeal to fans of George R.R. Martin. Best of all, it's already complete.
6. The Warlord Chronicles
Bernard Cornwell's The Warlord Chronicles reimagines Arthurian legend with historical realism. The trilogy—The Winter King, Enemy of God, and Excalibur—treats magic with ambiguity, grounding it in nature. It's gritty, smart, and offers a unique take on the classic tales of King Arthur and the Round Table.
5. The First Law Trilogy
Joe Abercrombie's First Law trilogy is a grimdark classic. With razor-sharp humor and deeply flawed characters, it explores the cyclical nature of violence. The series includes The Blade Itself, Before They Are Hanged, and Last Argument of Kings. For an introduction to modern grimdark fantasy, this is the perfect starting point.
