At the time of writing, there are 11 Star Trek shows (3 actively running) and 13 movies with a further show and a movie 'special event' in development.
With that in mind, it's no wonder that people come to this subreddit on a regular basis to ask where should I start?
This page is intended to be a spoiler free, quick start guide for people starting their journey through the Star Trek franchise.
We hope you find it useful, and please do contribute to the subreddit with your questions as you take your own journey; just be warned that you may see the odd spoiler.
Instead of telling you what you can and can't skip in an unwieldy list, we'll start with a quick rundown of the shows in the Trek 'canon', the initialisms you'll see over the subreddit to refer to them, how many seasons they have and when they aired:

Now we have that out of the way, here are a few suggestions:
##The "production" order.
If you're committed to watching everything eventually, and want to do it the "right" way, we recommend the following:
TOS^^1 → TAS → Films (1-6) → TNG → Generations (Film 7) → DS9 → First Contact (Film 8) → VOY → Films 9-10^^2 → ENT → Films 11-13^^3 → DSC → PIC → LD → PRO → SNW
^1 It's often recommended to skip "The Cage" on your initial watch-through. It was an unaired pilot and most of the footage was recycled into the two-parter "The Menagerie" (watch it later for the novelty, though!).
^2 The Movies 7, 8, 9 and 10 feature the TNG cast, and can be watched anytime after TNG without spoiling anything from DS9, Nemesis however contains a Voyager spoiler.
^3 Films 11-13 The "Kelvin Timeline" Films take place in an alternate timeline and can be watched anytime; however, there are a lot of references and easter eggs to the prime timeline.
Late TNG and early DS9 (as well as late DS9 and early VOY) were on the air at the same time, (an episode from each came out each week). Consequently, their story lines take place at the same time. If you want to watch it in the order it was aired on TV then this list is for you. It should be noted that nothing is lost/gained by watching each series one at a time in the order above due to the nature of 90s syndicated television.
Other popular suggestions
If you're not super keen on older television shows, or you're looking for a way to hook a significant other, there are several other approaches that come up.
Start with TNG
TNG → DS9 → VOY → Films 8-10 → ENT → TOS → TAS → Films (1-7) → Films 11-13 → DSC → PIC
This method is for those that think (or have found) that they struggle with the production value of TOS, ease yourself in with something a bit more modern and then go back to the start once you've developed a ~~lifelong obsession with~ fondness for the universe.
The Next Generation was the start of the Berman era of Star Trek in the late 80's (despite Star Treks creator Gene Roddenberry having the reigns for the first couple of seasons). It had much higher production values than The Original Series, and it set the tone and style for the following three shows. While TOS is mentioned, referenced, and characters from it even appear, this won't affect your enjoyment of those episodes because of how ubiquitous TOS characters are throughout pop culture. You'll definitely come to appreciate those episodes a little more after watching TOS though.
Start with a more modern show
This usually means starting with either ENT, DSC or SNW. This method is for those that really don't like older, slower-paced TV shows, or find black bars on the side of the screen a barrier to enjoyment. ENT has good effects and more modern pacing (along with less reused stock footage of the ship for the ship lovers out there). DSC ties in a fair amount with TOS- but can be safely watched before it without missing out on or spoiling anything big.
Enterprise takes place chronologicallybefore all other series. It references a lot of things from the other series though, and for maximum enjoyment should be watched after. But if you (or whomever you're trying to turn into a Trekkie) has a hard time getting into older series, this is a good way to get started. Many a Trekkie was created with this method.
NOTE: Picard is also a "modern" series, and while it can be enjoyed on it's own, there are considerable references/callbacks to the older series, including several main characters. So it's usually recommended to at least be familiar with TNG first.
Child Friendly
Star Trek contains a fair amount of adult themes and content, especially the newer shows with their higher production budgets and lack of television broadcast restrictions. Your parental boundaries may be different from ours, so to be safe; we recommend watching any live-action show episodes yourself before watching them as a family (despite TOS, TNG, DS9, VOY and ENT being marketed as family-friendly).
You can, however, safely watch Star Trek Prodigy with your family. It's specifically aimed at a younger audience (but is enjoyable for adults as well)!
Chronological order or Air Date
ENT → DSC → SNW → TOS → TAS → TNG → DS9 → TNG → DS9 → TNG → DS9 → TNG → DS9...
Did you watch Star Trek during it's original run and aren't worried about being spoiled, but don't really remember everything?
This is a list that was created by /u/jkeysgamer of every episode and movie in in-universe chronological order. It's not really recommended for newcomers, because it jumps around a lot, but can be fun for the adventurous types.
This is a list of every episode and movie by air date, while it will make more sense to a newcomer to watch it this way, opposed to in-universe chronologically, it's still quite the task for a casual viewer. (Special thanks to /u/busfahrer for making this site)
I started with TNG just because I've seen clips of Q. Worth it.
I have since finished TNG and am a couple episodes into TOS. Suprisingly TOS is not as bad as expected. It kinda holds up and the quality is pretty dang good on Netflix, again to my surprise.
Not sure I am gonna watch many of the other shows. I tried Discovery and Picard and I'm not really hooked. They are not bad, just eh. I do want to watch all the old movies though, right after I finish TOS which will probably take me a few years :D
I would at least touch on VOY, it needs a bit to get going, just like TNG I suppose, but it's solid. And the big, big payoff is watching DS9 after that. DS9 is fantastic, but it only gets better with the context from VOY and TNG.
Can you give a (spoiler free if possible) reason for why you would recommend watching VOY before DS9 instead of the other way around? I assumed that VOY might contain spoilers for DS9 since it aired later.
First, DS9 is straight up better. Peak Star Trek in my opinion, so it's nice to end on a high note. Again, not that VOY is bad or anything, but if DS9 is 10/10 Star Trek VOY is more like 8.5/10.
Second reason is world building. Really there isn't that much overlap as far as specific parts of the story is concerned, it's more that DS9 is so great because it turns some things that are taken for granted on their heads. VOY is useful because it kind of goes into that direction a little bit, with the conflicts that necessarily arise on a small ship far from home, and because you literally just learn more about the world/universe, whatever you want to call it, and the more context you have the better DS9 gets.
Very minor spoiler, both shows feature conflicts with the Marquis and the contrast, as well as the lack of contrast on how these conflicts are handled is very interesting.
Thanks! Tbh I don't care much about the first reason. I've been planning to eventually get around to watch at least ENT and some of the newer shows, so I probably won't be finishing with DS9 regardless. So far I've been following more or less the "start with TNG" ordering in the OP, and am now in season 3 of DS9. Do you think it would still be a gain to start VOY or am I already through the looking glass, i.e. does the latter add more to the earler seasons? If it's mostly about the world building and not the story I might give a rough version of the "chronological viewing order" a try and see if I enjoy it.
There's this weird cultural norm that says TOS is extremely cheesy, Shatner hams up every episode, the sets are all terrible, and it isn't worth watching. It's sad because TOS is my favourite and it has so many interesting stories, and Kirk is such a cool captain. Even TAS is worth a watch, especially the episode Yesteryear!
It's a real shame TOS got shafted by season 3, and we never got more of its peak due to diminishing budget. That's what networks love doing though, they can never appreciate a good thing until it's been off the air for decades and people are clamouring for more.
I would highly recommend anyone starting off with a collection of some of the best or most relevant episodes of TOS, as well as some of the poor ones like Spock's Brain. I've found at least the bad TOS ones are interesting, but bad TNG ones can be just boring.
