(Pierre) Adolphe Delattre (or De Lattre) (; 12 February 1805, Tours – 3 January 1854, Nice) was a French ornithologist.
Between 1831 and 1851 he made several expeditions to America, where he was particularly interested in collecting hummingbirds. He named a number of new species, either alone or with Jules Bourcier. In 1839, with naturalist René Primevère Lesson, he described seven species of hummingbird. Avibush Historiae Adolphe Delattre & Bourcier Jules - Birds
