Scouse is the accent and dialect of English found in the northern English city of Liverpool and adjoining urban areas of Merseyside and northwestern Cheshire. The Liverpool accent is highly distinctive and sounds wholly different from the accents used in the neighbouring regions of Cheshire and rural Lancashire. Inhabitants of Liverpool are often called Scousers.

The word Scouse was originally a variation of lobscouse (probably from the north German sailor's dish Labskaus), the name of a traditional dish of mutton stew mixed with hardtack eaten by sailors.

Lancashire has one of the most diverse selections of spoken accents of any English county or region. This is thought to be due to the large amount of immigration into the Liverpool area from Ireland, Wales, the Isle of Man, Scotland, other parts of northern England inland from it, in the eighteenth and nineteenth centuries. The influence of these speech patterns was strong in Liverpool, distinguishing the accent of its people from those of surrounding Lancashire and Cheshire.
