Todd Walker (1917 – September 13, 1998) was an American photographer, printmaker and creator of artists' books who is known for his manipulated images and for his use of offset lithography to produce individual prints and limited-edition books of his work.

In 1970 Walker accepted a one-year teaching position at the University of Florida. Seven years later he moved to Tucson and taught at the University of Arizona before retiring in 1985.

While in Arizona, Walker began working with some of the first Apple computers, and he used his technical skills to create some early 3-D images of his work and to create a book in which the text was mostly generated by the computer.   He wrote his own computer programs and later made use of software primarily designed for cartography. With these techniques he was able to create digital works that blurred, inverted and obscured the original image, making it into an expressive rather than detailed representation of reality.
