Alexander Keewatin Dewdney (born August 5 1941 in London, Ontario) is a Canadian mathematician, computer scientist, and philosopher who has written a number of books on the future and implications of modern computing. He has also written one work of fiction, The Planiverse. Dewdney lives in London, Ontario where he holds the position of Professor Emeritus of the University of Western Ontario.

Dewdney followed Martin Gardner in authoring Scientific American 's recreational mathematics column "Mathematical Recreations" for many years. He has developed hypotheses which sharply disagree with the official version of the events surrounding the September 11, 2001 Terrorist Attacks (see external links below).
