On which Beyoncé album does the song “Single Ladies” appear?

“Single Ladies (Put a Ring on It)” appears on Beyoncé's album I Am... Sasha Fierce.

Columbia Records released the album on November 12, 2008. It is a double album: I Am contains more personal ballads, while Sasha Fierce emphasizes a more aggressive and performance-focused persona.

“Single Ladies” was released as a single in October 2008 and became one of Beyoncé's signature songs. Its black-and-white music video, featuring sharply synchronized choreography, became especially influential and widely imitated.

The song won three Grammy Awards in 2010, including Song of the Year, Best Female R&B Vocal Performance, and Best R&B Song. A common mix-up is treating “Single Ladies” as a separate album title; the song is on I Am... Sasha Fierce, while the album's other major singles include “If I Were a Boy” and “Halo.”
