Clarence Petersen de la Motte (born 1892, date of death unknown), commonly C. P. de la Motte, was a sailor originally from Bulli, New South Wales. During his early career, he served aboard the New Zealand barque Northern Chief and the steamship Warrimoo. From 1911 to 1914, during the Australasian Antarctic Expedition, he served as Third Officer aboard the SY Aurora, under John King Davis. Expedition Commander Douglas Mawson named Cape De la Motte, in George V Land, after him. De la Motte joined the Aurora again in 1916, and served as First Officer during the rescue of the Ross Sea component of the Imperial Trans-Antarctic Expedition, for which he was later awarded the Polar Medal.
