Martha-Bryan Allen (April 30, 1903 – July 29, 1985) was an American stage actress, active during the 1920s.

[citation needed] Allen attended classes at the American Academy of Dramatic Arts in New York City[5] before making her Broadway debut on January 9, 1922, playing Angelica in Leonid Andreyev's He Who Gets Slapped.

She played Lucy Blake in Gypsy Jim, a three-act play by Oscar Hammerstein and Milton Herbert Gropper, Appolonia Lee in Sophie Treadwell's O, Nightingale, and Myrtle Carey in The Carolinian by Rafael Sabatini and J. Harold Terry.

In 1925 Allen was chosen to play the title role in John B. Hymer and Le Roy Clemens' Aloma of the South Seas, but was replaced by Vivienne Osborne shortly before the play's New York debut.

[6][5] Shortly after her marriage in 1926 to Lewis Arthur Cushman Jr., Allen chose to retire from the stage.
