Waterdeep is an adventure module published in 1989 for the Dungeons & Dragons fantasy role-playing game.

Waterdeep is a Forgotten Realms scenario which takes place in the city of Waterdeep, where the player characters seek to return the Tablets of Fate to the almighty god Ao in the final adventure of the FRE series.

[1] FRE3 Waterdeep was written by Douglas Niles, with a cover by Clyde Caldwell, and was published by TSR in 1989 as a 32-page booklet with a d three pane outer folder.

In the February–March 1990 edition of Games International (Issue 13), Dave Hughes criticized that the adventure "sticks rather too closely to its source, using dialogue, descriptive passages and, unforgivably, all the characters from the novel as Non-player characters."

He also pointed out that whatever the players did, non-player characters took credit for saving the Realms at the end of the adventure.
