Condomínio Aeronáutico Monte Cristo Airport (ICAO: SJ3M) is a private aeronautical condominium located in or near Boa Vista, the capital of Roraima state in northern Brazil. It is registered with Brazilian aeronautical authorities and serves private aircraft owners and aviation enthusiasts rather than scheduled commercial passengers. Aeronautical condominiums are a uniquely Brazilian concept in which private landowners maintain aircraft hangars and residential properties alongside a private airstrip, functioning as a gated community centered on aviation. Monte Cristo follows this model, catering to general aviation operations in the Roraima region.
