What is the title of Beyoncé’s 2008 studio album that includes “Single Ladies”?

Beyoncé’s 2008 studio album containing “Single Ladies (Put a Ring on It)” is I Am... Sasha Fierce.

The album was released in November 2008 as a double album. Its two discs presented contrasting sides of Beyoncé’s musical persona: the “I Am...” disc focused more on ballads and personal material, while the “Sasha Fierce” disc emphasized more energetic performance songs.

“Single Ladies (Put a Ring on It)” became one of the era’s most recognizable pop songs. Its black-and-white music video, featuring tightly synchronized choreography, became especially influential and widely imitated. Other major songs from the album included “If I Were a Boy,” “Halo,” and “Diva.”

The album title is sometimes shortened incorrectly to Sasha Fierce. That phrase is only the second half of the official title. Beyoncé later retired the Sasha Fierce alter ego, explaining that she no longer needed that stage persona to perform confidently.
