Helen Westley (born Henrietta Remsen Meserole Manney; March 28, 1875 – December 12, 1942) was an American character actress of stage and screen.

[2] Westley's early career activities included performing in stock theater and in vaudeville around the United States.

[2] Westley was an organizer of the Washington Square Players, debuting with that group on February 19, 1915, as the Oyster in Another Interior.

[2] She was a founding member of the original board of the Theatre Guild,[1] and appeared in many of its productions, among them Peer Gynt, and some of their productions of plays by George Bernard Shaw— Caesar and Cleopatra, Pygmalion, Heartbreak House, Major Barbara, The Doctor's Dilemma and The Apple Cart.

She appeared in the original Broadway productions of two plays which, after her death, turned into classic Rodgers and Hammerstein musicals: Green Grow the Lilacs, which became Oklahoma!, and Liliom, which became Carousel.
