Irreemplazable is the first extended play by American recording artist Beyoncé. Comprising Spanish, English and Spanglish re-recordings of songs from her second studio album B'Day (2006), it featured as a bonus disc for the United States deluxe edition of B'Day, before being released separately on August 28, 2007 by Columbia Records. It was produced by Cuban American musician Rudy Pérez who also helped with writing the songs in Spanish. Copies purchased from Walmart also contain a DVD featuring Beyoncé's concert and television performances and behind-the-scenes footage.

Irreemplazable received a mixed review from Allmusic's Andy Kellman, who criticized its lack of content and the fact that the EP was released several months after the deluxe edition of B'Day. Irreemplazable peaked at number 105 on the Billboard 200, and has sold 57,000 copies in the United States. It also appeared on the Top R&B/Hip-Hop Albums, the Top Latin Albums and the Latin Pop Albums charts. "Bello Embustero" including on the album was nominated for Record of The Year at the Latin Grammy Awards of 2007.

Growing up in Houston, Texas, Beyoncé was surrounded by the Spanish language, and learned some Spanish as a child, which she later forgot. When re-recording songs for Irreemplazable, Beyoncé's vocal coach provided the Spanish lyrics phonetically, and each line was recorded up to four times for the EP. Beyoncé has stated that she intends to take up Spanish lessons in the future. She said of the EP's recording, "This is such an honor for me to be able to connect with all my fans. I had so much fun singing in Spanish. It reminded me of growing up in Houston".The Denver Post's John Wenzel interpreted the release of Irreemplazable as "an effort to meet the exploding market for Spanish language music".
