The Optare MetroDecker is an integral twin-axle double-decker bus produced by British bus manufacturer Optare since 2014. The bus bears resemblance to the Optare MetroCity, sharing similar interior and exterior features. The MetroDecker was designed as the successor to the Optare Olympus and Scania OmniDekka double-deckers, which were both discontinued in 2011, however unlike these, the MetroDecker is only available in integral form.
Optare initially aimed to have MetroDeckers in service in London by the end of 2014 and sales of over 100 MetroDeckers within eighteen months of launch; this did not occur, with no orders placed until June 2018.
