A common problem faced by characters with Identity Amnesia is that they no longer recall their own name. A character struggling to find their identity may become involved in several related tropes under Memory Tropes and The Nameless.
Usually the character will be able to find their original name and identity by the end of the story. However, if this character loses their memory in the backstory, it is possible that they never truly recover their old identity and make use of a new Nom de Guerre. Another character may help them, and they go through a Meaningful Rename and/or Naming Ceremony.
This is a Sub-Trope to both Identity Amnesia (they cannot recall who they are) and The Nameless (they have no name). Super Trope to Take Away Their Name, where a character's name has been stolen, generally using magic. Can also be a Downplayed Trope to Identity Amnesia, if the character remembers everything about their past except their name.

- When the dragons of the Inheritance Cycle learned that the thirteen dragons of the Forsaken had turned against their own kind and were actively helping the Forsaken to kill and enslave their own kind, the free dragons grew angry. They gathered their power and performed one of their inexplicable works of magic. Somehow, they stripped the Thirteen of their names. From that moment on, no one could remember, read, write, or speak any name belonging to those dragons. Common names, true names, nicknames, everything. The dragons themselves could not even say "I like this" or "I dislike that", because to do so would be to name themselves. As such, stripped of identity, five of them descended into insanity and all of them slowly lost the ability to properly think.
- In Jonathan Strange & Mr Norrell the character called "Stephen Black" is apparently not actually named Stephen Black, or so it would seem according to the rules of magic, because 'Stephen' was a slave name and not his true name given to him by his mother at his birth, which has been lost. As such, Magic considers him to be "The Nameless King", which is problematic because there is also a historical figure prevalent in the story, the Raven King, who was also given a slave name that was not his real name, John Uskglass, and is also referred to as "The Nameless King". Spells meant to address the latter Nameless King accidentally affect the former Nameless King.

- In Pact, Maggie Holt is tricked into giving her True Name to a fairy, causing the fairy to become Maggie Holt while she becomes simply "girl in scarf".

- In Pathfinder, monks with the Monk of the Healing Hand archetype gain the "True Sacrifice" ability in place of their normal capstone - a Sacrificial Revival Spell which also erases all record of the monk's name, prevents it from ever being written or spoken, and makes it impossible to return the monk to life (even by resurrection effects that explicitly cannot be negated by any means, such as the direct intervention of a deity). Given the many ways to revive the dead which are available much earlier and don't require any kind of sacrifice, this has lead to jokes that its real capstone is "You get to forget you ever played a monk".
- Mega Man Zero: In the first game, the protagonist is awakened from his long slumber with some amnesia, including his name. He's repeatedly told that "You're Zero, the legendary Reploid" but he's not sure if he's really the Zero that the Resistance wanted (the Resistance took him into their place). At the end of the third game (where he encounters issues regarding his past and identity), he finally asserts "I am Zero".

- In Touhou Project, Junko's special ability is the ability to purify beings to a priordial state by removing their True Name. She used this power on herself, too, in order to turn herself into an Anthropomorphic Personification of pure resentment, which is why she's the only character with no Boss Subtitles.
- Given its popularity with pieces involving wandering samurai, this trope shows up in Way of the Samurai, where 'Nameless' is the default name given to the player's ronin character. You can always choose to change it, but the character is apparently some kind of amnesiac swordsman, so it fits.
- Dark Souls II: The Great Old Ones are so old that their names have been lost to history. The fact that the Duke's Dear Freja has a proper name is a hint that it is not a true Great Old One. The Great Old One is actually the fossilized dragon that Freja and her kin are using as a nest.
