Letters from a Flying Machine is an album by American singer-songwriter Peter Mulvey, released in 2009. Letters from a Flying Machine is a collection of new songs and spoken-word "letters" by Mulvey, the letters written while in flight to his nieces and nephews.

AllMusic's review of the album wrote of the spoken word sections "Most are painful to listen to, lacking the grace and lighthearted humor that mark his songwriting," but wrote the songs "aren't as heavy-handed, even when they take on weighty subjects.
