Fornells is a village located in a bay in the north of the Balearic island of Menorca, Spain. Fornells is estimated to have a population of about 1000 people which increases in the summer due to tourism. Fornells' native people are known as Fornellers in the Catalan language and in Spanish.

Fornells Bay is deep, measuring 5 kilometres long and 2 kilometres wide. The narrow entrance regulates the force of the open sea. Sufficiently narrow to offer protection, the entrance allows water to enter the bay while restricting the waves. The wind is not so easily restrained. The surrounding hills are not high enough to keep out the Tramontane (Tramontana in Catalan), which has shaped the rocks and bent the trees over until the branches almost touch the ground.

Having several small beaches around the bay, the harbour offers a number of aquatic activities for tourists, including boat trips, catamaran excursions, kayaking and windsurfing.

The annual fiesta de Sant Antoni is held on the fourth weekend in July.
