"Smack That" is a song by American singer/songwriter Akon from his second studio album Konvicted (2006). The song, which features a guest appearance from American rapper Eminem, was written by Akon, Mike Strange, Luis Resto and Eminem, with the latter also helming the song's production. The collaboration came after the two artists meet during a recording session for a Shady Records artist. The song received praise from contemporary music critics for being a great club song.

"Smack That" was released as the first single from Konvicted on September 26, 2006. Commercially, the song reached number one on ten record charts and peaked inside the top ten in nine, including the Billboard Hot 100, where it peaked at number two. It received several gold and platinum certifications and sold over 3 million downloads in the United States. The song earned a Grammy nomination for Best Rap/Sung Collaboration.

Akon met Eminem in 2006 during his recording sessions for Snitch with rapper Obie Trice, a Shady Records signee at the time, and the two became fast friends. Akon wanted him to be on "Smack That", but knew about Eminem's qualms on being featured on too many songs. After receiving a call from the rapper saying he was ready to go, Akon flew out to Detroit. On recording with Eminem, Akon stated that it was "no different than working with any of the other artists, really."

"Smack That" was written, produced and programmed by Eminem, with additional writing from Akon, Mike Strange and Luis Resto. Strange and Resto also played the keyboards present on the track. Strange worked with Tony Compana to record the song, which took place at 54 Sound in Detroit, Michigan, where Strange also mixed the song with Eminem. "Smack That" is an upbeat R&B and hip hop song that has been described as "a real summer party song."
