The Arnardalshamar Tunnel is a tunnel in Iceland, located in Westfjords along Route 61. It has a length of 30 m and was opened in 1948. It was the first manmade tunnel in Iceland and it is also the shortest. It cuts through a basalt dike known as Arnardalshamar, between Skutulsfjörður and Álftafjörður.
