Arnamul (Scottish Gaelic: Arnamuil) is a stack off the west coast of Mingulay in the Western Isles, Scotland.
Although precipitous, sheep were grazed on its relatively flat summit during the human occupation of Mingulay.
[1] Haswell-Smith (2004) states that the name means "erne mound".
[1][3] It was ascended by a party of hill baggers in April 2018.
