Field Day is a studio double album by English multi-instrumentalist and composer Anthony Phillips, released in October 2005 by Blueprint Records.

The project was conceived in September 2001, when Phillips decided to start on a proposed "quickie" instrumental guitar album.

[2] Phillips took each acoustic guitar he had and practised for two or three hours each day, "in a state of great excitement but chronic rustiness".

By early December 2001, he had enough material to work with, and his pieces featured not only a 6-, 10-, and 12-string guitar, but the cittern, English and Greek bouzouki, charango, and mandolin.

[4] At one point, Phillips considered the idea of releasing the music on Field Day across two separate albums to break it up, but became aware of the possibility of one containing most of the strongest material than the other, resulting in an unbalanced set.
