The Forbidden Street is a 1949 British melodrama film directed by Jean Negulesco and starring Dana Andrews, Maureen O'Hara, Sybil Thorndike, Fay Compton and A. E. Matthews.

Set in Victorian London, it tells the story of a wealthy young woman who marries a poor drunken artist and struggles to make ends meet; after his death, she takes in a lodger, with whom she falls in love.

In late-1800s London, the well-to-do Adelaide (Maureen O'Hara), over the objections of her family, marries her drawing teacher, impoverished artist Henry Lambert (Dana Andrews), and moves into his flat in the run-down street Britannia Mews.

Adelaide expects Henry to finish painting his masterpiece and blossom into a prominent artist, so that she can prove to her family that he did not seek to marry her for her money.

Estranged from her family and running out of money, Adelaide finally confronts Henry, who reveals that he romanced most of his wealthy female art pupils and that he does not love her and simply acquiesced to her insistence that they marry.
