Milton Mapes is a band that formed in Austin, Texas in 1999. The band was named after band member Greg Vanderpool's grandfather.

Singer/guitarist Greg Vanderpool and bandmate Roberto Sánchez, both veterans of Dallas’ Deep Ellum music scene, subsequently spent a year in Nashville compiling songs that would make up Milton Mapes' debut release The State Line (2001). The 7-song CD was well received by regional press and radio, drawing comparisons to Neil Young (Harvest) and Bruce Springsteen (Nebraska).
