"Logan's Law" is a short work by Harry Turtledove, first published in the collection We Install and Other Stories. It is a literary work (as opposed to genre fiction Turtledove usually writes) exploring the relationship between a recently divorced educator and a grad student.

The story begins with the "meet-cute" of Steve Whortleberry and Jen Barkman, after Jen gets lost. From there, the story follows basic romantic beats as the two have a successful date. The title of the story comes from one of Whortleberry's friends, Ed Logan, who, upon his own divorce, and feeling intimidated by entering the dating scene again, concludes that "all the good ones are taken." Whortleberry spends the story worried about "Logan's Law", but concludes at the end of the story that it isn't absolute.
