What name did Beyoncé use for her performance alter ego?

Beyoncé used the name Sasha Fierce for her performance alter ego.

She described Sasha Fierce as a more confident, uninhibited side of herself that appeared onstage. The concept became especially prominent around her 2008 double album I Am... Sasha Fierce. The album separated reflective ballads associated with Beyoncé’s personal side from more aggressive and dance-oriented material associated with Sasha Fierce.

The idea helped explain the contrast between intimate songs and high-energy performances, although Beyoncé later said she no longer needed the alter ego because she had integrated that confidence into her own personality. The name therefore belongs to a specific period of her artistic presentation rather than being her permanent stage name.

“Queen B” is a common fan nickname, but it is not the alter ego referenced by the album title. Blue Ivy is Beyoncé’s daughter, and “Honey Bee” is not the established name of this performance persona. Sasha Fierce is the canonical answer tied to Beyoncé’s 2008 album and its visual branding.
