GP5 is a format used to store projects made in the specialized Guitar Pro 5 software. Such a document may contain a single tablature for a solo or bass guitar, but also more complex projects containing a complete score for many stringed instruments. Tablature is a simplified notation system for stringed instruments, alternatively used in place of the traditional notation.

The GP5 format can also be imported by other programs (including Harmony Assistant or KGuitar). Guitar Pro was developed by Arobas Music.
