What is a case of a memorable dungeon you especially liked?

Might be a bit cheating, but the Dungeon of the Mad Mage is pretty fun to read through, at least.

Yeah - I have a soft spot for longstanding dungeons whose layout canonically changes and bored, foolhardy, or desperate adventures can just pit themselves against while regular people place bets on their demise. Undermountain is a great example, as is the Starstone Labyrinth in Golarion. I particularly like when the goal can be varied - the dungeon can have a specific item the PCs need, or they have to prove themselves inside to earn some entity's/organization's favor, or going through it is the best route to get somewhere the PCs need to be in the nick of time, or they're forced to run inside to escape some calamity, or they end up inside completely unwittingly etc.

The Death House from Curse of Strahd. It's not particularly GOOD dungeon, I just like how hilariously deadly it is for a starting dungeon.
As for a dungeon I like for itself, I'd say the Forge of Fury.

Are we counting conversions? Forge of Fury is 3e, but I also liked it a lot (have only played it in 3e though).

It was reprinted in the Tales of the Yawning Portal. It's one of my favorites as well.

Call me crazy, but I have a soft spot for the Tomb of the Nine Gods in Tomb of Annihilation. Just a massive, 6 level mega-dungeon filled with deadly traps and puzzles galore. There's surprisingly little combat in the actual dungeon, and you can't leave to resupply. Its all about the traps and puzzles. You gotta be aware of what's going on at almost all times, or you'll either lose all your gear, kill your team mates due to a curse, or just die. I basically model my proper boss dungeons off of it. Much to my party's dismay.

My favorite was Red Hand of Doom. It is 3rd ed.

I really liked Sunless Citadel. The difficulty isn't too hard or too easy, there's a decent variety of challenges and ways to approach things, the length isn't too long nor too short. Just overall a great starter dungeon. (Like Forge of Fury this one was also reprinted in Tales of the Yawning Portal).

I liked the 5e version of white plume mountain. Bit cheesy with all the weird puzzles and riddles, but it fitted out table very nicely and we had a blast. As a DM I loved the side scenario from Princes of the Apocalyps where the party had to defend a homestead against rampaging orcs (ok, not a dungeon in the strict sense of the word, but oh well). Planning, strategy, combat but also lots of RP opportunities. There is something for every type of player.

If we're talking favorite of all time, I have to go all the way back to 1e and say Dark Clouds Gather. It introduced Aarakocra and was a great blend of all three pillars (before we even knew the pillars existed). It was also pretty short and could be completed in 6 - 8 hours.

If you want 5e... I've got nothing. I haven't really enjoyed any of them. Doing nothing but homebrew now.

Forge of Fury is pretty good. My favorite dungeon no longer exists, as my friend from high school who DM'd it has lost it. This was a tale that grew in telling.

Another excellent dungeon was in issue 9 of a UK based zine, white dwarf maybe?

Dark Odo and the Licheway. Very good.

Slave Pits of the Undercity and really the whole A1-A4 "Against the Slave Lords" series was great.

A3 was kinda meh and ends in a genuinely terrible railroad (the party FINALLY gets to the bad guys, but instead of a climactic battle they get knocked unconscious by knockout gas, no saving throw), but the other 3 were all really fun, creative, and structurally very different adventures. A4 was the original "Party has to get out of a dangerous place w/o their gear" adventure, and I'm sure its frustrating for players but its great fun for the DM and then the central volcano of the island erupts just in time for the final battle.

They came out way before 5e, but at least the first 2 have updates (or at least update guides) online you can get.

For "since 5e", I really, really like "Temple of the Opal Goddess". A nobleman on an archeological expedition is kidnapped by orcs who send a surviving servant back with a ransom note, and the party is hired to save him. It sets up as a "base assault/rescue" adventure but there's more going on than it initially seems. A ton of backstory and character-building which is annoying if you want a one-off to run quickly, but its rich and interesting and has a bunch of fun ideas you can add to a campaign if you have time.

Temple of the Basilisk Cult is a nice, solid dungeon. Does everything you want without cruft. It's also free, which boosts the rating for me a bit.

I think it is a pretty good dungeon, too, and how it works fits the "was set up by the same person who built the Tomb of Horror, at a different point of his career" backstory extremely well.

It's not D&D, but it's 5e engine, for the Adventures in Rokugan, Tomb of Iuchiban. It is a randomly generated room dungeon. It has a start room, then 4-5 outer rooms (of about 8 options), then a fixed center room, then 3-4 inner rooms (of about 8 options) then a climax room. Topping off with the best surprise twist ending of any published adventure I've ever read.

[NecessaryWeevil]

I enjoyed the Hidden Shrine of Tamoachan because of the difficulty of resting. It made my spell selection and slot conservation really matter.
