The Complete Stargate Viewing Order (Chronological Timeline)
By Dr Ravenholm
Introduction
For years, the question has come up again and again among fans of the Stargate universe: what is the definitive viewing order? Not release order. Not “mostly chronological.” But a carefully constructed, internally consistent timeline that respects narrative continuity across every series, film, and web entry.
This post is my answer—but it’s also something more personal.
Stargate is my favourite show.
Not just in a casual sense—I’ve marathoned the entire franchise more times than I can count. It’s a constant return point. A universe I always find myself stepping back into.
And it all started with a very specific memory.
I went to see Stargate on opening night with my grandad at the old Canon Cinema in Monkseaton.
That moment—the lights going down, the first activation of the gate—never really left me.
Everything that follows comes from that place: a long-standing love for the world, the characters, and the idea that somewhere out there… the gate is still spinning.
Why This Order Matters
Watching Stargate in strict release order works—but it misses something important: the simultaneous evolution of its storylines.
By the time you reach later seasons, especially when SG-1 and Atlantis overlap, events are happening in parallel:
- Decisions made on Earth directly affect Pegasus
- Technology developments carry across shows
- Character arcs intersect across series boundaries
A proper viewing order restores that sense of a living, breathing shared universe.
“The Stargate isn’t just a device—it’s a narrative bridge between worlds, timelines, and consequences.”
What This Timeline Includes
This list is comprehensive. It covers:
- The original film
- All ten seasons of Stargate SG-1
- All five seasons of Stargate Atlantis
- Both seasons of Stargate Universe
- The films Stargate: The Ark of Truth and Stargate: Continuum
- The prequel web series Stargate Origins: Catherine
It is built to reflect:
- In-universe chronology
- Cross-series synchronization
- Narrative continuity

A Glimpse at the Structure
To give you an idea of how this timeline is constructed, here’s how the early progression unfolds:
- Begins with Stargate Origins: Catherine
- Moves into the original Stargate
- Flows directly into Stargate SG-1 Season 1
- Continues sequentially until the first major crossover point
- Then begins alternating between SG-1 and Stargate Atlantis episode-by-episode
By the mid-point of the franchise, the structure becomes:
- Interwoven episode sequencing
- Parallel story arcs
- Strategic placement of films between episodes
This is where most viewing guides fall apart—and where this one is most precise.
Key Crossover Era (Why It’s Important)
The most critical section of the timeline occurs during:
- SG-1 Seasons 8–10
- Atlantis Seasons 1–3
This is where:
- The Atlantis expedition begins
- Earth technology advances significantly
- The Ori and Wraith arcs develop in parallel
Watching these episodes in isolation loses narrative weight.
Watching them in this order reveals:
- Cause → effect across galaxies
- Shared stakes across teams
- A unified escalation of conflict
The Films in Context
The two concluding films are not standalone—they are direct continuations:
- Stargate: The Ark of Truth resolves the Ori storyline
- Stargate: Continuum serves as a time-travel epilogue
Their placement in the timeline is deliberate and essential.
The Final Phase: Universe
After the conclusion of SG-1 and Atlantis, the story transitions into:
- Stargate Universe
This marks a tonal and structural shift:
- More serialized storytelling
- A darker, survival-focused narrative
- A deeper exploration of Ancient technology
Placed correctly, it feels like a natural evolution—not a disconnected spin-off.
A Quick Side Note: Stargate Network
If you enjoy exploring the Stargate universe beyond the shows, I’ve also put together a separate post on the Stargate Network video game project.
It’s a fascinating fan-driven recreation of the gate system and world-building that captures a lot of what made the series special—particularly that sense of stepping through the gate into the unknown.

Closing Thoughts
This timeline is the result of careful alignment—not guesswork.
But more than that, it’s built from years of watching, re-watching, and genuinely loving this universe.
It respects:
- Internal chronology
- Narrative intent
- Cross-series continuity
If you’ve never experienced Stargate this way, it will feel different. More cohesive. More deliberate. More complete.
“Across galaxies, across time, across three series and multiple films—the Stargate was always telling one story.”

If you’re planning a full re-watch—or your first journey through the gate—this is the way to do it.
