Ruth M. Erb Hoffman (1902 – May 9, 1968) was an American artist and sculptor, based in Buffalo, New York.

In 1947 she had a joint show with fellow Buffalo artist Virginia Tillou, titled "Flower Variations".

"She is particularly adept at representing flowers within the setting of a room, arranging them in skillful reference to a pair of chairs, a windowsill with a view beyond, a porch railing.

"[5] Another reviewer wrote, in 1950, that "Ruth Hoffman's landscapes have a radiance about them that could bring any dull and comfortless north room in which they were hung the brilliance of a conservatory.

[3] In Buffalo, she worked from a studio over the garage at her mother's house on Main Street.
