Mabel Adrienne Morrison (March 1, 1883 – November 20, 1940) was an American stage actress of the early 20th century.

"[3] Morrison first appeared on stage at 6 months of age when her mother held her during a production of The Cricket on the Hearth.

[3] In 1905, she appeared as Nat-u-ritch, an Aboriginal American woman, in the play The Squaw Man with William Faversham.

[6] Morrison retired from the theater in 1926, but made a brief return in May 1940 to appear in Grey Farm at the Hudson Theatre.

"[13] In October, 1939, Morrison's residence in Lyme, Connecticut, was attached as a result of a $25,000 suit by a playwright who alleged that she "failed to report all proceeds" from a play.
