Alexander George Findlay (January 6, 1812 - May 3, 1875) was an English geographer and hydrographer active in London during the middle part of the 19th century. Findlay was born in London to the Findlays of Arbroath, Forfarshire, a family long associated with nautical trades. Findlay's father, Alexander Findlay (apprentice to John Russell) was one of the original fellows of the Royal Geographical Society. The son, Alexander George Findlay, devoted himself to the compilation of geographical and hydrographical works, publishing various nautical works as well as historical atlases. In 1844 he was elected a fellow of the Royal Geographical Society. Most of Findlay's early nautical work was completed in association with the London geographical and print publishing firm of Laurie and Whittle. Following the 1858 death of Richard Holmes Laurie, Findlay took over the business, republishing many updated versions of established charts well into the late 19th century.
