"Empty Walls" is a song by musician Serj Tankian. The song was released as the first official single and first track off of Tankian's debut solo album Elect the Dead. The song has been described as a "traditionally pummeling rocker".

"Empty Walls" was released on September 10, 2007 as a digital download and September 25 as a CD single. It can also be found on a 2 track Reprise promo issue dated September 4, 2007 as well as in edited form on promotional copies that have been sent out to radio stations.

An acoustic version of the song also appears on the limited edition of Elect the Dead. The "Victorious Club Mix", as featured on the single, was produced by DJ LethalRush.

The music video for the single was released onto Serj Tankian's official YouTube link on October 26, 2009. The video, which shows activity in a children's playroom that echoes the events of the September 11 terrorist attacks and the subsequent war in Iraq, contains an amended version of the last verse where it repeats "empty walls" instead of "fucking walls" and "goddamn walls".

All tracks written by Serj Tankian.

Serj released one of the videos on September 11, 2007, matching the video's War on Terrorism theme. The music video was directed by Tony Petrossian and was uploaded to YouTube on September 12, 2007. The video shows young children playing in a daycare center with their play imitating the War on Terrorism.

The video opens with a felt Homeland Security Advisory System scale (accompanied by a seal reading "U.S. Department of Playground Sekcureity"), followed by a young girl building two towers of blocks. A boy launches a toy airplane into the towers, knocking them down and upsetting the girl, and she is shown to want revenge.
