What stage name represents Beyoncé's alter ego on I Am... Sasha Fierce?

Sasha Fierce is the stage name representing Beyoncé’s alter ego on I Am... Sasha Fierce.

Beyoncé’s third studio album, released in 2008, was divided into two discs: I Am... and Sasha Fierce. The first side emphasized more personal ballads, while the second presented a bolder, more performance-driven persona. The album’s structure framed Sasha Fierce as a character Beyoncé used to separate her private self from her stage presence.

The album includes “If I Were a Boy,” “Halo,” “Diva,” and “Single Ladies (Put a Ring on It).” It became Beyoncé’s third consecutive number-one album on the Billboard 200 and produced several internationally successful singles.

Beyoncé later said that she no longer needed the alter ego after becoming more comfortable with her performance identity. “Sasha Fierce” should not be confused with Beyoncé’s nicknames “Queen Bey” or “Yoncé,” which are not the album’s alter-ego name.
