Daniell Peninsula () is the large peninsula between Cape Daniell and Cape Jones on the coast of Victoria Land. It is an elongated basalt dome similar to Adare Peninsula and Hallett Peninsula and rises to 2,000 metres (6,600 ft). It is partly separated from the Victory Mountains by Whitehall Glacier, which is afloat in its lower reaches, but is joined to these mountains by the higher land in the vicinity of Mount Prior. It was named by the New Zealand Geological Survey Antarctic Expedition, 1957–58, after Cape Daniell, and by analogy with Adare and Hallett Peninsulas.
