As I Was Going Down Sackville Street: A Phantasy in Fact is a book by Oliver St. John Gogarty. Published in 1937 by Rich & Cowan in the UK and by Reynal and Hitchcock in the US, it was Gogarty's first extended prose work and was described by its author as "something new in form: neither a 'memoir' nor a novel". Its title is taken from an obscure Dublin ballad of the same name, which was "rescued from oblivion and obloquy" by Gogarty's erstwhile friend James Joyce, who recited it for Gogarty in 1904 after hearing it in inner city Dublin.
