Book Four: Balance is the fourth and final season of the animated television series The Legend of Korra by Michael Dante DiMartino and Bryan Konietzko. It consists of thirteen episodes ("chapters"), all animated by Studio Mir. The episodes were made available on the Nickelodeon website and other online outlets each Friday beginning on October 3, 2014 and premiered on Nicktoons on November 28, 2014. Critical reception of Book Four, as of the series in general, was positive.

Book Four is set three years after the previous season. It deals with Avatar Korra's journey of self-discovery following the physical and psychological injuries she incurred in the fight with Zaheer and with unrest in the Earth Kingdom where Kuvira, formerly a security officer in Suyin Beifong's service, seeks to seize power by military force.

The season is then followed by the graphic novel trilogy Turf Wars, that picks up immediately after the series finale.

After Nickelodeon cut the budget for season 4 by about the amount required for one episode, DiMartino and Konietzko decided to include a clip show episode, which reuses previously produced animation, instead of letting many of the creative staff go. Inspired by Samurai Champloo s clip show episode "The Disorder Diaries", they chose to frame a series of edited clips from the previous seasons of The Legend of Korra with about five minutes of new animation. Aired as episode 8, "Remembrances", the clip show was also intended as "a lighthearted romp" similar to Avatar: The Last Airbender s episode "The Ember Island Players" before the series enters its dénouement.

Earth Empire has not been a contender in any CBUB matches.
