Good golly Onslaught is a mega event. You’d think the X-Universe was safe after Age of Apocalypse overturned all of reality, but nope, the story just gets bigger and wider reaching from there.
As it stands, Onslaught is one of the more poorly collected events inside Marvel Unlimited (many issues are missing). There is, fortunately, a reasonably straightforward (for the X-Men) way to navigate the event through collected trade paperbacks (and even an omnibus
I will lay out the trade reading order, and issue by issue comic book reading order for Onslaught below.

0 — X-Men: Prelude to Onslaught
(Not Recommended!)
As is the way of the X-Men, the Onslaught collected editions begin with a weird, complex, confusing twist.
Onslaught breaks down like this: There are three “Road to Onslaught” set up books, and then there are four “Complete Onslaught Epic” collections. As you know, the Road to Onslaught collection are above, with the Complete Epic below.
The prelude, then, is a prelude to what are already prelude books. It functions very much like a Wikipedia recap of the X-Men up until this point, with excerpts from comics and a fair amount of overlap with The Road to Onslaught.
As such, I do not recommend starting with this Prelude!
Here are the relevant issues excerpted within the prelude, if you’re interested:

I am glad this material is available to help me research the Onslaught event. I bought every comic that had the Onslaught logo on the cover of course to allow the consumer to know this edition was connected to the Onslaught event. I had the comic books packed away to reread one day then my son got older and began snooping thru my things and found my foot locker full of these comic books and you guessed it, My Son could care less and sold them when he moved out in 2012. I went to read them around 2020 and puff, gone. He swore for years until seeing my pain over the years finally admitted his actions this year. So now with your list I am going to began to rebuild some what of a collection of that event. Thanks
I swear I remember a scene where Mr Sinister was watching/spying on the the fight between Magneto & Prof X. He saw Magneto fall & an entity head towards Xavier. Mr Sinistet recognized the threat, attempted to stop it, but failed and quickly retreated.
This led to the creation of Onslaught. Am I missing remembering this? If not, what series & number was it featured in?
Generation X books #18 & #19 missing? Onslaught Impact
I originally decided to start reading Comics from the Heroes Reborn era. I enjoyed it but it made me want to understand what happened to lead to such an event. Well I realized it was Onslaught, and that it was an x-men villain.
I started reading x-men just because I really wanted to understand who this super powerful villain is.
Fast forward almost 2 years, I’ve reached the Onslaught saga, after reading EVERY SINGLE x-title or title that has a guess staring and xmen. It was a ridiculous road, but I fell in love with the x-men and I don’t see myself going back to reading random stories and big events, Im too engaged with the x-men.
Thank you CBH, your guides made it possible to start this road. Though lots and lots of what I’ve read never been mentioned here, but it’s understandable. I literally looked for every single comic book out there, and IM SURE I missed at least 25% of what is out there. The most important stuff are in the guide, and your way of structuring these made me understand how to slot in and out comics to make more sense. Without it, I’d probably not understand the x-men universe as I do.
Well. There are 20 plus years to cover, I’m excited.
Thank you CBH, without you I don’t know if I ever got to this point.
Um. You forgot uncanny xmen #335
OK, I’m wrapping up the Onslaught Omnibus. Your reading order through the whole Onslaught era has been invaluable, and my roadmap. But now I see no map ahead for Heroes Reborn and/or Heroes Return. What do I properly read next? I have MU, so that helps. Another map, please!! You are the best, and I will contribute as soon as I can one of these days (blame Social Security not keeping up with cost of living)! Stay well, Sir!
Hey- looking over this list – you are missing Uncanny X-Men #335 which I believe should be placed right after Onslaught: X-Men. Thanks for all the good work you put into this- the site is awesome.
