Beautiful Machines is the debut studio album by the Filipino alternative rock band Pupil, released on November 11, 2005 through Sony BMG Music Entertainment.

The album featured the singles “Nasaan Ka?”, "Dianetic", "Dulo Ng Dila", and "Gamu-Gamo".

Pupil was formed in 2005 as a spin-off of The Mongols, an underground band featuring Eraserheads vocalist Ely Buendia (vocals), Teeth guitarist Jerome Velasco (guitars), Yanni Yuzon (bass), and Bogs Jugo (drums).
