"No Connection" is a science fiction short story by American writer Isaac Asimov.
It was first published in the June 1948 issue of Astounding Science Fiction and reprinted in the 1972 collection The Early Asimov.
Written in May 1947, "No Connection" was Asimov's first non-Foundation, non-robot series story in more than two years.

It is implied that the arrivals may try to invade and colonise the lands occupied by Gurrows, and that they have developed nuclear weapons.
