This planet has no known canonical name.  While the information presented in this article is canonical, the planet described lacks an official name, thus the title is conjecture.

Reese's World was an uninhabited planet in the Milky Way galaxy which had a Stargate and was the homeworld of Reese and the Replicators. It apparently once had a human civilization, but their civilization was at some point completely destroyed by Replicators. (SG1: "Menace")
