Altiani (French pronunciation: [altjani]) is a commune in the Haute-Corse department of France on the island of Corsica.

Altiani is a commune in the Rogna in Quà microregion consists of cliff villages in the valley of Tavignano.

The village overlooks both the plain of Aleria and Corte as well as Venaco and therefore enjoys a remarkable panorama, very extensive and varied, over central mountain chain as well as the Tyrrhenian Sea.

300 metres upstream of the Genovese bridge on the N200 highway, the river is fed by the Limone stream whose source is under the Punta di Mangaio (1030 m - Sant'Andréa-di-Bozio).

The highest point of the commune is Punta Cervio (1,189 metres), Mount "à cheval" (straddling) both Focicchia, Piedicorte-di-Gaggio, and Altiani.

[3] The village is built on a rocky outcrop along the D314 road that winds through terraced houses between 560 and 640 metres above the valley of Tavignano.

Around 1520 the community of Santa Maria d'Altiani was part of the Pieve of Rogna in Quà which fell within the bishopric of Aleria.

The Pieve of Rogna we have spoken contains below the river (Tavignano) the following villages: Erbajolo, la Valle di Sera, Focicchia, la Lamella (la Mela), and Altiani where there is a convent of the Friars Minor, lo Petragio, Piedicorte di Gaggio, lo Lunello, Porra, lo Piano Buono, Pietraserena, Pancheraccia, Giuncaggio, and Carco; and this Pieve is densely populated and produces an abundance of corn, wine, oil, cattle, honey and fruit."

An experimental breeding station managed by the Office of Agriculture and Rural Development of Corsica (ODARC) has been implemented near the Genovese bridge on the RN200 highway at a place called Ponte.

Ten communes share this zone which has an area of 1,057 hectares stretching along the river from Aleria to the Noceta bridge.
