Hiiumaa (Estonian pronunciation: [ˈhiːumɑː]; German & Swedish: Dagö; Danish: Dagø; Finnish: Hiidenmaa) is the second largest island (989 km²) in Estonia. It is in the Baltic Sea, north of the island of Saaremaa, part of the West Estonian archipelago. Its largest town is Kärdla.
Hiiumaa is the main island of Hiiu County, called Hiiumaa or Hiiu maakond in Estonian. The Swedish and German name of the island is Dagö ("Day" island), Dagø in Danish — a calque of its old Finnish name Päivänsalo ("Day" island); compare Ösel (Yösalo – night island) for Saaremaa. In modern Finnish, it is called Hiidenmaa, literally Hiisi's Land. In Old Gutnish, it was Dagaiþ (day isthmus), from which the local North Germanic name "Daë" is derived.
Archaeological evidence of the first human settlement in Hiiumaa dates to the 4th century BC. The first documented record of the island of Dageida was made by contemporary chroniclers in 1228, when Hiiumaa and the rest of Estonia were conquered by Germanic crusaders. In 1254, Hiiumaa was divided between the Bishopric of Ösel-Wiek and the Livonian branch of the Teutonic Order, acting partly on behalf of the Hanseatic League.
The island was part of Swedish Estonia from 1563 to 1721, after which it passed to the Russian Empire as part of the Governorate of Estonia, though Dagö's Swedish population kept most of their privileges. Most of the island's previously numerous Swedish-speaking population emigrated or were "Estonianised" during the period of Imperial Russian rule, although a minority remains to this day. Estonian Swedes are also known as "aibofolke" (meaning island people in Swedish) or "rannarootslased" (meaning coastal Swedes in Estonian).

Hiiumaa Island was annexed by the Soviet Union in 1940, by Nazi Germany in 1941, and by the Soviets again in 1944. It was part of the Estonian Soviet Socialist Republic until the Soviet Union collapsed in 1991. During the Soviet era, Hiiumaa was declared a restricted zone, closed to foreigners and to most mainland Estonians. Since 1991, the island has been a part of independent Estonia.
Road transport from Estonian mainland to Hiiumaa involves a 90-minute (28 km) ferry crossing from Rohuküla to Heltermaa, which is 25 km by road from Kärdla. There are about 10 ferry departures a day. In the summer weekends, getting car space on the ferry usually requires advance booking. There are about 2 scheduled buses a day between Tallinn (the capital of Estonia) and Kärdla. In the winter, the island can be reached, conditions permitting, via a 26.5 km ice road (the longest in Europe) across the frozen Baltic Sea.
