Dragons in the Dungeons of D&D

[Jan van Leyden]

I can add the Oriental Dragon (Pan Lung) in the swamps of UK2 - Danger at Dunwater.

 

[MarkB]

The Red Hand of Doom includes climactic dragon encounters at the end of each of its story arcs, and at the entrance to the final dungeon, but I don't think any of those actually occur inside dungeons, so you may be able to disregard this one for your purposes.

The Slaying Stone for 4e has a brass dragon that's designed more as a social encounter and not for slaying, also

A few more...

X5 There is a red dragon in the Great Pass (X4 has a black dragon as a wondering monster as well)

I think Night Below has a dragon encounter in Book 2 as well. Don't have my box handy to check, though.

 

[M.L. Martin]

DL3 - Dragons of Hope; Blaize, brass dragon; unnamed shadow dragon
DL9 - Dragons of Deceit; various unnamed blue dragons

The shadow dragon does have a name--Whisper. And I believe DL9 also includes Cymbol the copper and Harkiel the Bender, a red.

Ravenloft--At least the ones I remember

RQ3 From the Shadows, Ravenloft Gazetteer II: Ebb, shadow dragon, mount for Azalin. (Gazetteer II introduces the possibility of a second, Gloom, as Ebb's mate and an Expy of Dragonlance's Whisper. )
The Forgotten Terror, nameless 1000-ft. red dragon (it's not a 'real' dragon, but a mental construct from the darklord's childhood fears)

 

[Holy Bovine]

the map in S2 White Plume Mountain had directions on how to get to Dragotha the Undead Dragon (sort of...)

 

[UselessTriviaMan]

Return to the Temple of Elemental Evil also has an unnamed white dragon listed as a possible random encounter.

CM2 - Death's Ride; Korbundar, blue dragon

Oh, how I despised that vile wyrm...

We haven't even touched Dungeon magazine; I know there are scads scattered throughout there (The 1st mag had a Red Dragon named Flame, as I recall, who returned for another adventure sometime later in the magazine series - #32?).

Dragon magazine also had Ed Greenwood's dragon series, but I don't recall if those were just the stat-up of dragons (Wyrms of the North was the series, if memory serves right), or if they included any actual adventures.
