The original The Walking Dead ended after 11 seasons, so there is no official Season 13 to count episodes for. The series finished with 177 episodes total.

What this means

  • If you meant the main AMC series, Season 13 does not exist.
  • If you meant a fan-made or spin-off version, tell me which one and I can help identify the episode count.

TL;DR: TWD’s main series has no Season 13; it ended at Season 11 with 177 episodes.
