What was the title of Beyoncé’s 2008 studio album released after the birth of her alter ego Sasha Fierce?

Beyoncé’s 2008 album was titled I Am... Sasha Fierce.

The album was released on November 12, 2008, as Beyoncé’s third studio album. It was structured as a double album: I Am... focused on ballads and more personal material, while Sasha Fierce emphasized an energetic, performance-oriented persona.

The title refers to Sasha Fierce, a stage alter ego Beyoncé described as emerging during performances. The album produced major singles including “If I Were a Boy,” “Single Ladies (Put a Ring on It),” “Halo,” and “Ego.”

The wording is sometimes shortened incorrectly to Sasha Fierce, but that is the name of the persona and the second disc, not the complete album title. The album helped make “Single Ladies” a global cultural phenomenon and earned multiple Grammy Awards at the 52nd ceremony.
