Alexander Goodman More FRSE FLS MRIA (5 September 1830 – 22 March 1895) was a British naturalist.
Born in London, More was educated at Rugby School, and matriculated at Trinity College, Cambridge in 1850. He did not graduate, however, though he remained at Trinity until 1855: periods of illness interrupted his studies. He did make contact with a number of botanists and ornithologists there. Then until 1867 he occupied himself with natural history. In that year he was appointed an assistant in the Natural History Museum of the Royal Dublin Society.
More's major work was Cybele Hibernica (1866), with David Moore.
