Þjóðhátíð (Icelandic pronunciation: [ˈθjouːðˌhauːˌtʰiːθ], "National Festival") is an annual outdoor festival held in Vestmannaeyjar island, Iceland, on the weekend before the first Monday in August. Locals and guests gather in Herjólfsdalur valley on the island of Heimaey for four days of various events, most prominently big stage concerts, bonfires, fireworks displays and the festival's signature Sunday night crowd singing.

In 2010 there was a record attendance of between 16,000 and 17,000 on the Sunday night. The local sports district association ÍBV (Íþróttabandalag Vestmannaeyja) organises and runs the festival.

Most participants stay in tents in and around the Herjólfsdalur valley. Hotels are also booked out as well as homestays being rented out for the weekend. Transport to and from the island is provided by the Herjólfur ferry to Landeyjarhöfn and flights from Vestmannaeyjar Airport. Private companies also operate smaller boat trips.
