Haa Alif Atoll is the code name based on the letters of the Maldivian alphabet commonly used to refer to the administrative division officially known as Northern Thiladhunmathi Atoll (Maldivian: Thiladhunmathi Uthuruburi) in the Maldives.

It is the northernmost of the 19 administrative divisions (known as "Atolls") of the country, and is the third-largest administrative division in terms of population and land area.

This administrative division consists of Ihavandhippolhu, the northernmost geographical atoll of the Maldive archipelago, and the northern section of Thiladhunmathi atoll. The capital of North Thiladhunmathi Atoll is the island of Dhidhdhoo where the Secretariat of North Thiladhunmathi Atoll Council is located.

Geography

The Northern Thiladhunmathi Atoll administrative division consists of a total of 43 islands spread over two natural geographic atolls, namely Northern Thiladhunmathi, and Ihavandhippolhu.

Northern Thiladhunmathi is the northernmost portion of the huge Thiladhunmathi Atoll. Thiladhunmathi Atoll was administratively divided into northern and southern divisions in 1958.

Ihavandhippolhu lies to the north of Northern Thiladhunmathi, with the Ihavandhoo Kandu channel separating the two, and is the northernmost atoll of the Maldives. It is a small natural atoll 22 km in length. It has 25 islands lying all around the boundary reef. One long barrier reef forms the western side of the atoll. There are several coral patches in the lagoon and the general depth in the centre is 20 to 30 fathoms (35 to 55 m).

Ihavandhippolhu is separated from the Lakshadweep Islands of India by the broad channel known as Māmalē Kandu (or Maliku Kandu).
