If you mean the last episode released so far , the anime is not finished yet ; as of the sources I found, it was still ongoing, with episode 1155 discussed in late 2025 and episode numbering continuing beyond 1140 in 2025 schedules.

Quick answer

  • There is no final episode of One Piece yet.
  • If you meant the latest episode available at the time of the sources , that was episode 1155 in a late-2025 discussion thread.

What this means

One Piece is still an ongoing series, so “the last episode” can mean either:

  • the most recent episode released , or
  • the final episode of the entire anime , which has not happened yet.

Tiny note

A lot of search results about a “final episode” are fan theories or jokes, not official ending information.
