"The Ugly Little Boy" is a science fiction short story by Isaac Asimov. The story first appeared in the September 1958 issue of Galaxy Science Fiction under the title "Lastborn", and was reprinted under its current title in the 1959 collection Nine Tomorrows. The story deals with a Homo neanderthalensis child which is brought to the future by means of time travel. Robert Silverberg later expanded it into a novel with the same title published in 1992 (also published as Child of Time in the UK).
