The Aston Martin One-77 is a two-door coupé built by Aston Martin.

It first appeared at the 2008 Paris Motor Show, although the car remained mostly covered by a "Savile Row tailored skirt" throughout the show, before being fully revealed at the 2009 Geneva Motor Show.

There was a limited run of 77 units as delivery started in October 2010^{[citation needed]}.
