Elektra Natchios (UK: /ˈnætʃiɒs/, US: /-oʊs/) is a fictional character appearing in American comic books published by Marvel Comics. Created by Frank Miller, the character first appeared in Daredevil #168 (January 1981). She is a love interest of the superhero Daredevil, but her violent nature and mercenary lifestyle divide the two.
The character is a highly trained assassin of Greek descent who wields a pair of sai as her trademark weapons. Elektra is one of Frank Miller's best-known creations, but subsequent writers' use of her is controversial as Marvel had originally promised to refrain from reviving the character without Miller's permission. She has also appeared as a supporting character of the X-Men's Wolverine and in other series and mini-series, as well as adaptations for the screen.
In the 2003 film Daredevil and its 2005 spin-off, Elektra, the character is portrayed by Jennifer Garner. Élodie Yung portrayed the character in the second season of Marvel's Daredevil and The Defenders (2017) for the Marvel Cinematic Universe.
