"One Armed Scissor" is the debut single by American post-hardcore band At the Drive-In, released in 2000 from their album Relationship of Command.

It was the first At the Drive-In song to be played regularly on a number of radio stations, and is considered to be one of the first emo songs to have achieved mainstream success.

According to a Channel V interview, a one-armed scissor is a mixture of "red bull and vodka", and that the song is about their tours told from the omniscient character named the one-armed scissor who sees their hardships they deal with while on tour.

The music video for this song contains all footage from live shows and the road in general.
