Chronology
Predecessor	Scania N94

The Scania N-series is a series of low-floor city bus chassis with straight-up, transversely mounted Euro IV or newer engine at the rear, built by Scania since 2006, replacing the Scania N94.

It is available as the N UB (N230UB, N270UB, N280UB) two-axle single-decker bus, the N UA tri-axle articulated bus, and the N UD (N230UD, N250UD, N260UD, N270UD, N280UD) two-axle double-decker bus. The double-decker variant is mainly built for use in the United Kingdom, and is available both as an integral product known as the Scania OmniCity, and as a separate chassis with Alexander Dennis Enviro400 bodywork.

The N230UD is the best selling variant of the N-series chassis, with Stagecoach in the United Kingdom being the largest customer. The N230UD was succeeded as the main model of the N-series family by the updated N250UD in 2015, which was launched with the updated Alexander Dennis Enviro400 MMC bodywork.

A gas-powered double-decker variant of the N-series chassis, known as the N280UD, is currently in development and is planned to be launched with Enviro400 MMC bodywork in 2016. Reading Buses will be the launch customer of what will become the United Kingdom's first ever gas-powered double-decker bus.
