Sir Thomas Edward Gordon KCIE KCB CSI (12 January 1832 – 23 March 1914) was a Scottish soldier, diplomat, and traveler. A British Army officer, he fought in India, served as a diplomat in Tehran, and travelled across the Pamirs. These days he is primarily remembered as an author of several books about India, Persia (modern day Iran), and Central Asia of the 19th century.
In 1873–1874, he participated in the Second Yarkand Mission led by Thomas Douglas Forsyth. The main goal of the expedition was to meet Yakub Beg, the ruler of Chinese Turkestan. Gordon also joined a party that traveled west to the Pamirs and Wakhan. Gordon was accompanied on the mission by John Biddulph, Ferdinand Stoliczka, Henry Walter Bellew, Henry Trotter, and R. A. Champman. In 1876 Gordon published his account of the expedition.
