Robert "Bob" Nastanovich (born August 27, 1967 in Rochester, New York, United States) is an American musician and member of the indie rock band Pavement, as well as former member of the Silver Jews, Ectoslavia, and Pale Horse Riders.

Pavement was an American indie rock band that formed in Stockton, California in 1989. The group mainly consisted of Stephen Malkmus (vocals and guitar), Scott Kannberg (guitar and vocals), Mark Ibold (bass), Steve West (drums) and Bob Nastanovich (percussion and vocals). Initially conceived as a recording project, the band at first avoided press or live performances, while attracting considerable underground attention with their early releases. Gradually evolving into a more polished band, Pavement recorded five full-length albums and nine EPs over the course of their decade-long career, though they disbanded with some acrimony in 1999 as the members moved on to other projects. In 2010, they undertook a well-received reunion tour.
