Star Wars Erotica: The Essential Guide to Interspecies Relations

Star Wars Erotica: The Essential Guide to Interspecies Relations is a 2020 erotica canon reference work written by Kooriv, and his second entry in his Essential Guides to Star Wars Erotica series following The Essential Guide to Erotica Characters. The work compiles information on the species and creatures of Star Wars Erotica, including many official species and numerous creations from the erotica canon and Legends erotica universes. It was released on June 15, 2020.

The work is framed as an in-universe compilation of details from Professor S. Rachilore's journal, edited by archivists of the Graf Archive, as noted in the Introduction ostensibly written by Tertiary Sub-Director Hischule Xohaes. The text features supposed "annotations" from Rachilore and other in-universe writers, commenting on their experiences with the species featured.

In addition to the 175 primary species and creatures featured in the work, the document also contains an appendix of an additional 105 "Species of Note", as well as a "Timeline of Alien Encounters" and a "Planet Reference List" charting the species' homeworlds and colonies cited in the text.
