Cosmo Cosmolino is a 1992 book by Australian writer Helen Garner. The book consists of three linked works: two short stories and a novella, though the author and critics have described it as a novel. It was first published in Australia by McPhee Gribble and was shortlisted for the 1993 Miles Franklin Award. It has been reported that the novel's title is Garner's favourite, and came to her in a dream.
