100 Acres of Sycamore is the third studio album by Irish singer-songwriter Fionn Regan, released on 8 August 2011 on Heavenly Records. Unlike Regan's previous album, The Shadow of an Empire, which featured mostly rock and roll songs, the album foregrounds an acoustic aesthetic, similar to that of his debut, The End of History (2006). Recorded in seven days, 100 Acres of Sycamore features a prominent string section throughout, and features backing vocal contributions from The Staves on the track, "North Star Lover".
