To paint the town red means to go out and celebrate with uninhibited energy, often staying out late and enjoying a few drinks along the way. The phrase’s exact origin is unknown, but the full expression is documented in print by the 1880s. That evidence gives us a reliable period for its use—not a precise date or person who coined it.
The wording turns a night out into a spectacular act of mischief: the town itself becomes the canvas, and red paint suggests a bold, rowdy transformation. By the late 19th century, the expression was being used for revelry rather than literal painting. Its meaning has remained flexible ever since. A celebration can be boisterous without being destructive, and no paint is required.
A popular origin story reaches back to 1837, when the Marquis of Waterford was said to have led a drunken rampage in Melton Mowbray, daubing buildings, a tollgate and a swan statue with red paint. The tale suits the phrase so neatly that it has proved hard to dislodge. But the account does not establish that the incident happened as described—or that it gave rise to the expression. The phrase’s appearance in print decades later leaves a gap, and there is no solid evidence linking the two. It is best treated as an entertaining legend, not a confirmed origin.
Today, you might say, “After the last exam, the whole group went out to paint the town red,” or, “They’re painting the town red to celebrate their anniversary.” The phrase endures because it makes a simple night of celebration sound vivid, communal and just a little bit wild.
