Matthias Nace Forney (March 28, 1835 – January 14, 1908) was an American steam locomotive designer and builder. He is most well known for the design of the Forney type locomotive. Locomotives that he designed served the elevated railroads of New York City for many years before that system converted to electric power. One example of a Forney 0-4-4T locomotive built in 1902 by Baldwin Locomotive Works has been restored for daily operations on the Disneyland Railroad in Anaheim, California, as the railroad's number 5, Ward Kimball. He died on January 14, 1908 in New York, New York.
