Decade of the Nail Spiked Bat is the seventh studio album by American power metal band Jag Panzer, released in 2003.

It comprises re-recordings of songs from the band's previous studio releases: the Jag Panzer EP (1983), Ample Destruction (1984), and Dissident Alliance (1994), two songs previously released on compilations, as well as the Shadow Thief demo and the album Chain of Command, both of which were previously unreleased at the time of the album's release.

The recordings for Decade of the Nail Spiked Bat came as a result of the band's inability to secure a deal to reissue their 1984 full length debut, Ample Destruction.

The band was able to come up with 15 songs for the album on their own, but had to consult third-parties for the remaining 5.
