This site is NOT a chronology - it is a viewing guide that will assist you through watching the entire franchise in in-universe story order, all the way from the 21st to the 43rd centuries, while making adjustments as needed to ensure an enjoyable viewing experience. It is not rigid - some episodes are shifted in the order to keep things as clear and fun as possible. The guide is updated regularly to stay current with new episodes.
By the end of this year we’ll have bid farewell to The Next Generation with the fantastic series finale “All Good Things,” we’ll have finally watched Enterprise’s far less popular finale “These are the Voyages…”, and we will have been introduced to The Dominion, the major story driver for most of Deep Space Nine.

This section has yet to be updated to the new, expanded and more detailed interface, but the list itself is correct and should still be of use.
Like Phase II was intended to do, and Discovery does again a few decades later, Star Trek Voyager is launched as the centerpiece of a new network: the short-lived UPN, home of Shasta McNasty and The Secret Diary of Desmond Pfieffer. Note that Voyager episode orders, particularly in season two, jump around a bit due to some production weirdness.
