What was Beyoncé’s alter ego called during the I Am... Sasha Fierce era?

Beyoncé’s alter ego during the I Am... Sasha Fierce era was called Sasha Fierce.

I Am... Sasha Fierce was Beyoncé’s third solo studio album, released in 2008. Its two-disc structure contrasted the reflective “I Am...” side with the more energetic “Sasha Fierce” side.

Beyoncé described Sasha Fierce as a performance persona that helped her become more uninhibited onstage. The concept connected to the album’s themes of public confidence, private vulnerability, and the difference between the performer and the person.

The album included major songs such as “If I Were a Boy,” “Halo,” “Single Ladies (Put a Ring on It),” and “Diva.” Sasha Fierce was not a separate singer or legal identity; it was a stage persona associated with Beyoncé’s high-energy performance mode.
