Kaafu Atoll is the code name (roughly equivalent to "Atoll K" in English) given to an administrative division in the Republic of Maldives which consists of the geographical atolls of Kaashidhoo Island, Gaafaru, North Malé Atoll and South Malé Atoll. As the two Malé Atolls are the main islands of the administrative district, the entire Kaafu Atoll administrative division is officially named Malé Atoll or Malé Atolhu in the Dhivehi language.
The capital of the administrative division is Thulusdhoo.
