Francis Joseph Christopher Sheehy Skeffington (né Skeffington; 23 December 1878 – 26 April 1916) was an Irish writer and radical activist, known publicly by the nickname "Skeffy". He was also the real-life model for a character in James Joyce's novel, A Portrait of the Artist as a Young Man. He was a friend and schoolmate of Joyce, Oliver St. John Gogarty, Tom Kettle, and Frank O'Brien (the father of Conor Cruise O'Brien). He married Hanna Sheehy in 1903, whose own surname he adopted as part of his name, resulting in the name "Sheehy Skeffington". They always showed their joined names unhyphenated, although many sources include the hyphen.
