Agoraphobic Nosebleed (abbreviated as ANb) is a grindcore band formed in 1994 in Springfield, Massachusetts, United States.

Its line-up has changed often over the years, with guitarist and drum programmer Scott Hull being the only continuous member. The current line-up includes vocalists Jay Randall, and Richard Johnson of Enemy Soil and Drugs of Faith, along with John Jarvis of Pig Destroyer and Fulgora on bass guitar. Agoraphobic Nosebleed is one of the most well-known drum-machine grindcore bands, and has influenced drum-machine grindcore as a whole.

On October 24, 2018, Kat Katz announced on Facebook that she was no longer a member of the band, because she is “tired of being bullied by dudes.” A few hours later, the band confirmed Katz’s departure on the official Agoraphobic Nosebleed Facebook page.
