Unhalfbricking is the third album by the British folk rock band Fairport Convention and their second album released in 1969. It is seen as a transitional album in their history and marked a further musical move away from American influences towards more traditional English folk songs that had begun on their previous album, What We Did on Our Holidays and reached its peak on the follow-up, Liege & Lief, released later the same year.

The album features several Bob Dylan songs, which he had not yet released. It also features what is arguably Sandy Denny's most notable achievement as a songwriter with the song "Who Knows Where the Time Goes?", which has been covered by many other performers and is now regarded as a classic. The only traditional song on the album, "A Sailor's Life", is seen as pivotal in the development of English folk rock music.

Changes in the line-up of the band, due not only to its musical direction but also to external events, mark this album as a turning point in the band's history. 1969 was a prolific year for Fairport Convention; from What We Did on Our Holidays to Liege & Lief within twelve months represented a major development.
