"Red Sector A" is a song by Rush that provides a first-person account of a nameless protagonist living in an unspecified prison camp setting. "Red Sector A" first appeared on the band's 1984 album Grace Under Pressure.

Lyricist Neil Peart has stated that the detailed imagery in the song intentionally evokes concentration camps of the Holocaust, although he left the lyrics ambiguous enough that they could deal with any similar prison camp scenario. The song was inspired in part by Geddy Lee's mother's accounts of the Holocaust.

Geddy Lee explained the genesis of the song in an interview:

The seeds for the song were planted nearly 60 years ago in April 1945 when British and Canadian soldiers liberated the Nazi concentration camp Bergen-Belsen. Lee’s mother, Manya (now Mary) Rubenstein, was among the survivors. (His father, Morris Weinrib, was liberated from the Dachau concentration camp a few weeks later.) The whole album “Grace Under Pressure,” says Lee, who was born Gary Lee Weinrib, “is about being on the brink and having the courage and strength to survive.”

Though “Red Sector A,” like much of the album from which it comes, is set in a bleak, apocalyptic future, what Lee calls “the psychology” of the song comes directly from a story his mother told him about the day she was liberated.

“I once asked my mother her first thoughts upon being liberated,” Lee says during a phone conversation. “She didn’t believe [liberation] was possible. She didn’t believe that if there was a society outside the camp how they could allow this to exist, so she believed society was done in.”

In a 1984 interview Neil Peart describes writing Red Sector A:

I read a first person account of someone who had survived the whole system of trains and work camps and Bergen-Belsen and all of that (...) through first person accounts from other people who came out at the end of it, always glad to be alive, which again was the essence of grace, grace under pressure is that through all of it, these people never gave up the strong will to survive, through the utmost horror, and total physical privations of all kinds.
