Millom is a town on the estuary of the River Duddon in Cumbria, England, which, in Victorian times, was merely a small hamlet by the name of Holborn Hill. The name is Cumbrian dialect for "At the mills".
The town is served by Millom railway station.
There are two nature reserves near the town, both of which are located on the Duddon Estuary; an internationally important area for wildlife and designated a 'Site of Special Scientific Interest' or SSSI. The Hodbarrow Nature Reserve is owned by the RSPB and is located to the south of the town, which in October 2005, saw the unveiling of its new public aid, with logos produced by local artists Stuart Edwards and Holly Parminter.
The Millom Iron Works Local Nature Reserve is located to the east of the town. Both reserves are important for Tern species and a number of wading birds and waterfowl. Hodbarrow is renowned for large numbers of wildfowl during the winter, especially Teal, Widgeon, Coot, Mallard, Tufted Duck, Pochard, Goldeneye, Red-breasted Merganser, and occasionally Long-tailed Duck, Eider, Goosander, Pintail and Shoveler. Various birds of prey can be seen hunting on both reserves throughout the year.
