Seltjarnarnes (Icelandic pronunciation: [ˈsɛlˌtʰja(r)tnarˌnɛːs] ) is a town and municipality in the Capital Region of Iceland. The municipality is located on a peninsula, bordered only by Reykjavík to the east. It is also the most densely populated municipality in Iceland.

It took on its current political form shortly after the Second World War and was formally created as a township in 1947. It is the smallest Icelandic township by land. The municipality's small land size relative to its population makes it Iceland's most densely populated municipality.
