Pg. 99 (also spelled pageninetynine) was a hardcore punk band from Sterling, Virginia on the outskirts of Washington, D.C. The band formed as a six-piece in fall 1997 and later expanded to an eight-piece. They occasionally would enlist the services of an additional musician or two for a live song but were never more than an eight-piece composed of two singers, three guitarists, two bassists and a drummer. Pg. 99 was known for their intense live shows.

Pg. 99 made many US tours and a European tour during their tenure. They released 11 records as a total over their various record companies.

After several US tours, a European tour, and numerous releases, they disbanded in May 2003. Before officially breaking up, Pg.99 booked Steve Albini of Shellac and Big Black as their producer for a follow-up to Document #8. Guitarist Mike Taylor cited struggles with maintaining a large line-up due to schedule conflicts, and issues with drinking as major reasons for why Pg. 99 broke up. Taylor also said, "It was like a dysfunctional family where a group of people needed to give each other some space and clarity." Four of the members would go on to perform in Pygmy Lush.
