There are four seasons of The Legend of Korra as released and marketed to viewers.

Quick answer

  • Officially: 4 seasons (called “Books”)
  • Total episodes: 52
  • Run: 2012–2014

Why you sometimes see “2 seasons”

Internally, Nickelodeon and the display “Legend of Korra is technically only 2 seasons long” have claimed that, from a production standpoint, there were only two larger production orders (each around 26 episodes), which were later split into four “Books” for broadcast and streaming.

So the confusion comes from two different ways of counting:

  • Production view : 2 big seasons, each split into 2 “Books” → 4 broadcast seasons.
  • Viewer/streaming view : 4 distinct seasons labeled Book 1–4, as shown on IMDb, Paramount+, Rotten Tomatoes, and most episode guides.

How the four seasons are structured

The series is organized into four “Books,” each with its own theme:

  1. Book One: Air – 13 episodes
  2. Book Two: Spirits – 14 episodes
  3. Book Three: Change – 13 episodes
  4. Book Four: Balance – 13 episodes

Total: 13 + 14 + 13 + 13 = 52 episodes.

Where you’ll see it listed

Most platforms and databases list:

  • IMDb : “4 seasons”
  • Paramount+ : Season 1, Season 2, Season 3, Season 4
  • Rotten Tomatoes : Seasons 1–4, sometimes labeled by Book (e.g., “Book Four – Balance”)
  • Wikipedia : Describes the show as having four books/seasons with 52 episodes total.

So if you’re asking as a viewer looking how many seasons to watch or stream, the correct answer is four. Information gathered from public forums or data available on the internet and portrayed here.
