Glaswegian or The Glasgow Patter is a dialect spoken in and around Glasgow, Scotland. In addition to local West Mid Scots, the dialect has Highland English and Hiberno-English influences, owing to the speech of Highlanders and Irish people, who migrated in large numbers to the Glasgow area in the 19th and early 20th centuries.

The Patter is used widely in everyday speech in Glasgow, and even occasionally in broadcasting and print. It is constantly evolving and being updated with new euphemisms as well as nicknames for well-known local figures and buildings.

Michael Munro wrote a guide to Glasgow Patter entitled The Patter, first published in 1985. With illustrations by David Neilson, and later by the Paisley-born artist and playwright John Byrne, the book became very popular in Glasgow. It was followed by The Patter - Another Blast in 1988, with The Complete Patter, an updated compendium of the first and second books, being published in 1996.

In the 1970s, the Glasgow-born comedian Stanley Baxter parodied the patter on his television sketch show. "Parliamo Glasgow" was a spoof programme in which Baxter played a language coach and various scenarios using Glaswegian dialogue were played out for laughs.
