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.

Ihavandhippolhu lies to the north of Northern Thiladhunmathi, with the Ihavandhoo Kandu channel separating the two, and is the northernmost atoll of the Maldives.

The atoll council was created in 2011 with the enactment of the Decentralization Bill, which saw the introduction of local governance to the country.

In Matheerah there is a famous shrine (ziyaraiy, mausoleum) which was visited formerly by the Maldive kings and their families in order to seek blessings.

Fishermen from Thuraakunu and from Minicoy often crossed the Maliku Kandu on their boats to visit each other's islands.
