The Flash Watch Order in the correct order

How to watch The Flash CW series and Arrowverse crossovers in order

Last updated: July 7 2026

The CW's The Flash is the cornerstone of the Arrowverse, following Barry Allen's journey from crime scene investigator struck by lightning to the fastest man alive. Nine seasons of thrills, heart, and time-travel adventures make the viewing order an important consideration.

The Flash premiered on The CW in 2014 as a spin-off from Arrow and quickly became the beating heart of the Arrowverse. Grant Gustin's Barry Allen is endlessly likeable, and the show balances superhero action with warm, character-driven storytelling. With nine seasons and dozens of crossover events with other Arrowverse shows, knowing the order matters — especially for the big annual crossover episodes.

🕐 Release Order

Watching in release order is strongly recommended. The show's major annual crossovers span multiple series, and missing them means missing significant story developments.

  1. The Flash Season 1 (2014–2015) — Barry becomes the Flash
  2. The Flash Season 2 (2015–2016) — Earth-2 and Zoom
  3. The Flash Season 3 (2016–2017) — Flashpoint and Savitar
  4. The Flash Season 4 (2017–2018) — The Thinker
  5. The Flash Season 5 (2018–2019) — Nora West-Allen arrives
  6. The Flash Season 6 (2019–2020) — Crisis on Infinite Earths crossover
  7. The Flash Season 7 (2021) — New Forces and a reborn multiverse
  8. The Flash Season 8 (2021–2022) — Armageddon crossover event
  9. The Flash Season 9 (2023) — Series finale

The story chronology aligns with the release order. The Flash's timeline is largely linear, though the show frequently explores time travel and alternate Earths.

📖 Story Chronology

Despite the show's heavy use of time travel, the main narrative follows a clear forward progression from Barry's origin to the series finale. Time travel events are presented as they happen within the story.

  1. Season 1 (2014–2015) — Origin: the particle accelerator explosion creates meta-humans
  2. Seasons 2–3 (2015–2017) — Multiverse exploration and the dangers of changing time
  3. Seasons 4–5 (2017–2019) — New villains and Barry's legacy
  4. Seasons 6–9 (2019–2023) — Post-Crisis universe and the final chapter

Which Order Should You Choose?

Watch in release order from Season 1. For the full Arrowverse experience, the major annual crossover events (The Flash vs. Arrow, Invasion!, Crisis on Earth-X, Elseworlds, Crisis on Infinite Earths) span multiple shows and are best watched as part of a full Arrowverse marathon. The Flash can also be enjoyed as a standalone series — its crossover episodes are designed to be followable without watching every other Arrowverse show.
