Vega is a municipality in Nordland county, Norway.
Vega was established as a municipality January 1, 1838 (see formannskapsdistrikt)
The municipality comprises 6,500 islands of the Vega Archipelago. Vega is also the name of the main island within the municipality. Its area is 163 km².
Early settlements on the main island date back 10,000 years, making it one of the oldest places of inhabitance in North Norway. Agriculture and fishing are at present as they were in the past, key fields of labour. Today's inhabitants are concentrated in Holand, Valla, Igerøy and Gladstad, the latter being the location of the municipal council and most of the island's commerce.
In 2004, the archipelago's cultural landscape was inscribed by UNESCO on the World Heritage List as representative of "the way generations of fishermen/farmers have, over the past 1,500 years, maintained a sustainable living in an inhospitable seascape near the Arctic Circle, based on the now unique practice of eider down harvesting." The oceanic climate and limestone bedrock has allowed 10 different species of orchids to grow in Vega, and 210 species of birds have been recorded at the archipelago. Eidemsliene nature reserve has many warmth loving species of plants and the most oceanic pine forest in North Norway (). Holandsosen nature reserve is an important wetland area with a shallow lake and soil rich in lime; 149 species of birds have been observed in this reserve which has a rich bird life all year (many birds use this as their winter quarter). Lånan nature reserve preserves many types of coastal nature and is a very important area for many species of birds; eider down harvesting is still practiced here ().
There is one hotel on Vega - the Vega Havhotell.
Until 1891 the name was written Vegø.
