Lieutenant-Colonel James Augustus Grant (11 April 1827 – 11 February 1892) was a Scottish explorer of eastern equatorial Africa. He made contributions to the journals of various learned societies, the most notable being the "Botany of the Speke and Grant Expedition" in vol. xxix of the Transactions of the Linnean Society. He married in 1865 and settled down at Nairn, where he died in 1892. He was buried in the crypt of St Paul's Cathedral. Grant's gazelle, one of the largest gazelles in Africa, was named after him.
