'West Ryder Pauper Lunatic Asylum' is the third studio album by British indie rockers Kasabian, which was first released on 5 June 2009.

The album is the first album by the band to not feature Christopher Karloff, the band's leading songwriter, following his departure during the writing stages of Kasabian's second album, 'Empire' (2006). Lead guitarist Sergio Pizzorno took over as the main force behind the band's song writing.

The album was nominated for the 2009 Mercury Prize. In October 2009, it was voted the best album of the year by Q Magazine.
