"Defender" is a song by Australian singer–songwriter Gabriella Cilmi, released as the third single from her second studio album Ten.

Jon O'Brien from Allmusic said that: "The epic beats of the Dido-esque power "Defender," offer a respite from the party atmosphere, but as competent as they are, Ten is much more interesting when Cilmi unleashes her previously hidden disco diva tendencies".

[1] The music video for "Defender" starts off with Cilmi with her back to the camera holding a microphone, a stage light is shining on her and a crowd can be heard cheering and applauding her.

Whilst walking through the corridor she takes off her jewellery and her dress leaving Cilmi in just her underwear and shoes.

She wraps black material around her wrists and is then seen walking down the corridor again only this time she is holding a katana and she has a scarf around her mouth.
