Arkanar is the capital of Arkanar Kingdom on a fictional unnamed planet described in " Hard to Be a God" ("Трудно быть богом") by Boris and Arkady Strugatsky. This planet is a part of the so-called Noon Universe and presents a world in a late feudalistic/ Renaissance stage (opposite to e.g. early feudalism of Saula). As stated, the planet has never been officially named so it is usually referred to by the name of the city where the action of the book takes place. Arkanar (planet) was discovered in the EN-2097 solar system in 2134 AD.
Very little is known about the planet as a whole, since the book only describes the events that happened in Arkanar shortly before the so-called "Arkanar Massacre" (see below). The planet has nine continents.
