Which alter ego gives Beyoncé’s 2008 album its title?

Sasha Fierce gives Beyoncé’s 2008 album its title.

I Am... Sasha Fierce is Beyoncé’s third studio album, released in November 2008. It is divided into two discs: I Am... emphasizes more personal ballads, while Sasha Fierce focuses on more energetic and confident performance songs.

Beyoncé described Sasha Fierce as a stage persona or alter ego that helped her become more fearless while performing. The concept was connected to the contrast between her private personality and her public performance identity.

The album produced major singles including “If I Were a Boy,” “Single Ladies (Put a Ring on It),” and “Halo.” It became a commercial success and won several awards, while “Single Ladies” became especially associated with its distinctive choreography and black-and-white video.
