Encore is the fifth studio album by American rapper Eminem. It was released on November 12, 2004, by Aftermath Entertainment, Shady Records, and Interscope Records. Its release date was originally set for November 16, 2004, but Eminem moved the release date to five days earlier after the album was leaked to the internet. As reflected on the album cover—Eminem taking a bow—the album was widely considered to be Eminem's final album of new material.

The album contains several lyrical themes, most notably Eminem's opposition to then-US president George W. Bush and a parody towards Michael Jackson. The album features more comedic themes and lyrics than Eminem's previous albums.

Critical reception of Encore was less favorable than Eminem's previous albums, with most of the second half being heavily criticized for its lackluster quality and lack of lyrical content, though "Mockingbird" and "Like Toy Soldiers" were particularly highly praised and retrospectively have been noted as being some of Eminem's best songs. The album has sold 11 million copies worldwide and was certified quadruple platinum by the Recording Industry Association of America (RIAA) on December 17, 2004.

Encore provoked some controversy over anti-Bush lyrics and lyrics that parodied and targeted Jackson, who was upset about Eminem's depiction of him in the video for "Just Lose It". Retrospectively, Encore is often considered to be one of Eminem's two worst albums alongside Revival.
