Esperantujo (IPA: [es.pe.ran.ˈtu.jo]) or Esperantio [es.pe.ran.ˈti.o] is a term (meaning "Esperanto-land") used by speakers of the constructed international auxiliary language Esperanto to refer to the Esperanto community and the activities going on in the language. When two people are speaking Esperanto, they are said to be "in" Esperantujo.
