John Frederick Baddeley (July 1854 – Oxford, 16 February 1940) was a British traveller, scholar and journalist, best known by his works on Russia and the Caucasus region.

 He was educated at Wellington College, Berkshire. After visiting Russia for seven months in 1879, Baddeley became the St. Petersburg correspondent for the London Standard, and began a lifelong relationship with that country, travelling widely and writing several important books on its history. In the summer of 1900 he made his first of several journeys to Siberia and the Russian Far East. He was a Fellow of the Royal Geographical Society, 1902-1940.
