Ross O'Carroll-Kelly is a satirical fictional Irish character, a wealthy South County Dublin rugby union jock created by journalist Paul Howard. The character first appeared in a January 1998 column in the Sunday Tribune newspaper and later transferred to The Irish Times. The series comprises twenty-one novels, three plays, a CD, two other books, a weekly podcast, and the newspaper column, as of 2023.

Ross O'Carroll-Kelly was something of a craze in Ireland, and his name has become a byword for all that is perceived to be wrong in Celtic Tiger Ireland. Though it is largely viewed as satire, there are those who view Ross O'Carroll-Kelly as a role model or an idol. Paul Howard has claimed some people have imitated Ross's friends pastime of driving through disadvantaged areas in expensive cars, shouting "Affluence!" at passers-by and throwing €5 notes out the window. Following Ross's move to The Irish Times, the Irish Independent began a similar column, OMG! featuring a female counterpart to Ross, in its Weekend supplement on 22 September 2007.
