The Sinners of Erspia is the fifteenth science fiction novel by Barrington J. Bayley.

The main character is the interstellar courier Laedo, who is stranded on the bizarre artificial planetoid Erspia (an anagram of "aspire").

The novel was completed in 1997 and was first published as a print-on-demand book in 2002.

Paul Di Filippo, reviewing the novel for Asimov's, described Bayley as "one of those shamefully overlooked sui generis writers that SF produces in abundance," concluding that The Sinners of Erspia was a "continually self-regenerating book.
