Vestmanna is a town in the Faroe Islands on the west of the island of Streymoy. It was formerly a ferry port, until an undersea tunnel was built from Vágar to Kvívík and Stykkið. The cliffs west of Vestmanna, Vestmannabjørgini are very popular for excursions by boat. A 'Vestmann' was a "Westman", or Gael in Old Norse. The original name was Vestmannahavn, i.e. "West-men's/Irish-men's harbour".
