This is the list of episodes for the animated television series The Legend of Korra. The series premiered on April 14, 2012, and ran for a total of 52 episodes. Like its predecessor Avatar: The Last Airbender, the series classifies each episode as a "chapter", but unlike the previous series, where each season was one "book", The Legend of Korra has two seasons, comprised of two distinct "books" each. The list is ordered by the release date of the original airing in the United States.

After averaging 3.9 million viewers for Book One: Air, The Legend of Korra received an order for twenty-six more episodes in July 2012. The show returned on September 13, 2013, with the television debut of the first two episodes of Book Two: Spirits. The first book of the second season, titled Book Three: Change, began airing on June 27, 2014, and ran for thirteen episodes. After a brief break, the fourth and final book, titled Book Four: Balance, premiered on October 3, 2014, and also ran for thirteen episodes.

The first two chapters comprised the series premiere.[1] As part of a special preview, these were made available on the site KorraNation.com during the weekend of March 24 and 25, 2012, twenty-one days before the official premiere. Nickelodeon also released the first part of the second episode of the series for online viewing on April 2, 2012, twelve days earlier than the television air date.[2] After both earlier releases, iTunes released a season pass and the first two episodes on April 3, 2012. For a short period of time, episodes one and two were available for free downloading. Episodes are available in both high definition and standard definition.[3] All early releases were exclusive to the United States.

Book Two debuted on Nickleodeon on September 13, 2013, with a double episode, as had been done in the previous book. During its run, eight episodes aired as part of hour-long specials, and select episodes were screened in advance at the San Diego and New York Comic-Cons. In addition, after the series' fans completed a challenge from Korra Nation on Tumblr, the final two episodes of the book were uploaded to Nick.com at midnight on November 16, six days before their television debuts.

Book Three debuted on Nickelodeon with the first three episodes on June 27, 2014, followed by two episodes each on July 11 and July 18. The book moved to online release after the eighth episode aired on July 25, with one episode per week until the two-part finale on August 22. The final five episodes eventually aired on Nicktoons Network just after the premiere of Book Four.

Book Four debuted on Nick.com and the Nick App on October 3, 2014, with one episode released every week until the two-part series finale on December 19. Like the previous book, Book Four's episodes made their television debuts on Nicktoons Network, running on Fridays from November 28 to December 19.
