Killsadie was a Minneapolis based post-hardcore band from 1997 to 2001. Known for their large number of line-up changes, and for being the spawning ground for a number of later indie rock bands, such as Minus the Bear, Pretty Girls Make Graves, Sharks Keep Moving, and These Arms Are Snakes.

The band's name was taken from an incident at a party. Founding drummer Erin Tate was informed by his brother Knol (guitarist) that a girl named "Sadie tried to kill [him]". Tate responded that "someone should kill Sadie."
