Monster (the Ryan Murphy true‑crime anthology series on Netflix) already has multiple seasons out, and the newest season, Monster: The Ed Gein Story , premiered on Netflix on October 3, 2025.

Which “Monster” are you asking about?

The phrase “when is monster on Netflix” can mean a few different things. The answer depends on which one you mean:

  • The Ryan Murphy Netflix anthology about real‑life killers (Dahmer, Menendez, Ed Gein).
  • The classic anime “Monster” by Naoki Urasawa, which has appeared on Netflix in various regions.

Below are the key possibilities so you can match what you’re actually looking for.

1. Ryan Murphy’s Monster (Dahmer, Menendez, Ed Gein)

Netflix now treats this as an anthology simply titled Monster , each season about a different real‑world killer.

  • Season 1 – Dahmer – Monster: The Jeffrey Dahmer Story
    • Released on Netflix September 21, 2022.
  • Season 2 – Monsters: The Lyle and Erik Menendez Story
    • Released on Netflix September 19, 2024.
  • Season 3 – Monster: The Ed Gein Story
    • Released on Netflix on October 3, 2025.
* Netflix has promoted it as the “third and darkest season yet,” returning as part of the Monster anthology.

So if your question is about “when is Monster on Netflix?” in the sense of the Ed Gein season , it is already available now and dropped globally on October 3, 2025.

2. The Monster anime on Netflix

If you meant the anime series “Monster” (about Dr. Tenma and Johan), that is a completely different show. Key points:

  • Fans reported that all 74 episodes became available on Netflix starting January 1, 2023 in multiple regions including North America, France, Germany, the UK, and India.
  • Availability is region‑locked and can change over time, so whether it is “on Netflix” for you right now depends on your country and current licensing.

If your question is “When did the Monster anime come to Netflix?”, the answer is January 1, 2023 in many major regions.

Here’s a simple side‑by‑side to clarify which “Monster” is which and when each hit Netflix:

Forum / trending angle

On forums and social media, the question “when is Monster on Netflix” tends to pop up in two waves:

  • Around late 2022–2023 , when the anime Monster finally appeared on Netflix in more countries, many users shared regional availability and workarounds.
  • Around 2024–2025 , the phrase shifted to mean the new seasons of Ryan Murphy’s Monster , especially the anticipation leading up to the Ed Gein season’s October 3, 2025 premiere.

So, in 2026, if someone asks “when is Monster on Netflix?”, most people will assume they mean the Monster anthology’s latest season , which is already out as of October 3, 2025.

TL;DR:

  • Ryan Murphy’s Monster (Ed Gein season) → on Netflix since October 3, 2025.
  • Monster anime → arrived on Netflix in many regions on January 1, 2023 ; current availability depends on your country.
