Ross O'Carroll-Kelly is a satirical fictional Irish character, a wealthy South County Dublin rugby union jock created by journalist Paul Howard.

The series comprises twenty-one novels, three plays, a CD, two other books, a weekly podcast, and the newspaper column, as of 2023.

Due to the wide variety of esoteric slang used in the novels, a glossary ("ThesauRoss") appears as an appendix to Ross O'Carroll-Kelly's Guide to (South) Dublin: How To Get By On, Like, €10,000 A Day.

Though the basic idioms are derived largely from standard Hiberno-English, the South Dublin accent as represented by Howard has distinctive features: Although the main satirical targets of the columns are affluent South Dublin dwellers, elements of working-class culture (sometimes called skanger culture) are also parodied, again, primarily through language.

Paul Howard has claimed some people have imitated Ross's friends pastime of driving through disadvantaged areas in expensive cars, shouting "Affluence!"
