Súðavík is a fishing village and municipality (Súðavíkurhreppur) on the west coast of Álftarfjörður in Vestfirðir, Iceland (66.03°N 23.00°W).
The population of Súðavík is around 190.

On January 16, 1995, an avalanche fell on the village early in the morning (around 6:25 am) and destroyed several buildings, most of them residents houses. Fourteen people were killed (including eight children) and twelve were injured. Severe snow storms made the rescue work difficult and dangerous. The final survivor was rescued 23 hours after the avalanche had fallen, and the search continued into the evening of January 17. A disaster relief fund was established, and within a week, the Icelandic public had donated 300 million kroner (about $3,000,000) to the relief effort.

The same winter, two more avalanches fell from Traðargil, destroying several houses; the areas hit had already been evacuated, so no more lives were lost. Avalanches fell from many other gullies and mountainsides during the avalanche cycle that winter.

At a public meeting on January 23, 1995, it was decided that the village should be rebuilt at a safer location. The existing properties within the danger zone were sold to the Icelandic government, and construction work on the new village began on August 23. By winter of 1996, 51 new houses had been built, and eight more had been moved from the old residential area. The industries in the area were relocated along with the residents, whith the exception of the freezing plant, which continues to operate in a similar manner as it did prior to the avalanche. Many of the properties in the old town are now rented out to tourists in the summer months.

The village´s main industries now are fishing, fish processing and tourism.
