Cucuí Airport (ICAO: SWKU) is a small general aviation airstrip located in Cucuí, a remote village in the far northwestern tip of Amazonas state, Brazil, near the tripoint border of Brazil, Venezuela, and Colombia. The airstrip serves the broader municipality of São Gabriel da Cachoeira, which administers this vast and sparsely populated region of the Upper Rio Negro. The facility is a basic, unpaved or minimally developed airstrip primarily used for light aircraft, military operations, and essential supply flights to an area with virtually no road access. It plays a critical logistical role for the indigenous communities and Brazilian military personnel stationed near the border. Due to its extreme remoteness, the airport has no commercial airline service and minimal infrastructure. Access to Cucuí by air is the most practical means of travel, as the only alternative is a lengthy river journey along the Rio Negro.
