The Damsel Errant is the Distaff Counterpart of the Knight Errant, a Stock Character of the Chivalric Romance. They form a complementary pair; he is seeking adventure and she knows where adventures are to be found. Not to be confused with the Damsel in Distress, though she probably knows a few in need of succor.
The Damsel Errant may Walk the Earth, often accompanied by a faithful servant, she may head for the Standard Royal Court and demand that The Good King send a Knight in Shining Armor to right an injustice in his realm, or she might set up her pavilion near a fountain or other spot where knights are known to pass. She is seldom named or given any kind of background; basically she is a plot device for putting the knight where the action is. She rarely becomes a love interest normally leaving the knight once they've run out of adventures, often at or near the spot where he first encountered her. In some cases there are hints that the lady is of magical origin.

- King Arthur legend: The three ladies encountered by Sir Gawain, Sir Ywain and Sir Marhous in the Forest of Arroy are classic examples of the Damsel Errant. They are also evidence that such ladies need not be young, as one was 60 years old!
- According to Sir Thomas Malory and the Vulgate, Sir Lancelot couldn't move more than a step without tripping over a Damsel Errant, who would then proceed to lead him into deadly peril.
- Dame Lynette came to court to fetch a knight to defend her sister, Lady Lyonesse. In Malory, Sir Gareth married Lady Lyonesse; in Tennyson, Lynette.
- In Edmund Spenser's The Faerie Queene, Una fetches Saint George to defend her parents and their kingdom. They do become a couple.
- P. G. Wodehouse gently mocks the convention with Yvonne in his "Sir Agravaine"; she is a distinctly plain girl, and the quest she brings Sir Agravaine into turns out to be of a highly surprising nature.
- Naturally, Gerald Morris has quite a few in his Arthurian retellings, The Squire's Tales, although they have a tendency to take on Action Girl characteristics too. Notable examples include Eileen, Lynette, Ariel, and Lynette's Generation Xerox daughter.
- The Three Questing Ladies play this trope straighter, although in different ways. For example, the eldest of them trains her knights before letting them embark on adventures, and the youngest gets hers killed (by encouraging them to fight other knights until they die valiantly, at which point she latches onto the winning knight, and so on until she returns to the meeting place).
- A Connecticut Yankee in King Arthur's Court: A fair maiden by the name of Alisande comes to King Arthur's court seeking a brave knight to go with her and rescue her 44 princesses, locked up in yon tower and guarded by three fearsome ogres. This being a satire written by Mark Twain, they turn out to be pigs, and the ogres are farmhands.
- If you go by her words in "The Doctor's Wife," the TARDIS is this to the Doctor.
The Doctor: You didn't always take me where I wanted to go.Idris: No, but I always took you where you needed to go.
- In Dragon Age, the plot of the Origins DLC Witch Hunt revolves around the Warden's attempts to track down their former companion (and possible love interest), Morrigan. If romanced previously, the Warden can decide to follow her through the Eluvian to parts unknown.
- Iris in Lufia II: Rise of the Sinistrals might fit into this trope, although she is more of a guide than a partner.
- Arthur, King of Time and Space, of course, features many of the ones from Arthurian myth, including Lynette and Croisette from Lancelot's Knight Errant period. During the Grail quest, the Damsels Errant and Wise Old Hermits have a complete checklist of how the quest is supposed to go, so they can push knights in the right direction for the next bit.
- Teyla the Sorceress in He-Man and the Masters of the Universe (1983).
