What was the name of Beyoncé’s alter ego used during the I Am... era?

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

The name appears in the title of her 2008 third studio album, I Am... Sasha Fierce. Beyoncé described the project as a double album: the “I Am...” disc focused more on personal ballads and emotional material, while the “Sasha Fierce” disc emphasized a bolder, more performance-oriented persona.

The concept helped distinguish Beyoncé’s private and stage-facing sides during that period. Songs associated with the Sasha Fierce disc include “Single Ladies (Put a Ring on It),” “Diva,” and “Ego.” “Halo” and “If I Were a Boy” belong to the I Am... side.

Sasha Fierce is not Beyoncé’s legal name, a separate recording artist, or the title of a later album. Beyoncé later said she had retired the alter ego, explaining that she no longer needed a separate persona to access confidence onstage.
