Frenchman's Creek is a 1944 adventure film adaptation of Daphne du Maurier's 1941 novel of the same name, about an aristocratic English woman who falls in love with a French pirate.

The film was released by Paramount Pictures and starred Joan Fontaine, Arturo de Córdova, Basil Rathbone, Cecil Kellaway, and Nigel Bruce.

After her husband's friend, Lord Rockingham, makes unwanted advances she take her two children to their remote estate in Navron, Cornwall.

And so she dresses as a cabin boy and joins the pirate crew on an expedition to capture a richly laden merchant ship (the Merry Fortune) belonging to one of her neighbors.

The attack is a success but the news of it brings Dona's husband, Harry, and the evil Rockingham to Cornwall, disrupting her idyllic romance.

Bosley Crowther of The New York Times called the film "somewhat slow in starting", but observed that the production values were suitably extravagant and invited readers to "catch a post-chaise to the Rivoli and check your think-cap at the door if you want a two-hour excursion in fancy-pants cloak-and-sword escape.

"[9] John Lardner of The New Yorker wrote: "Not having read the Daphne du Maurier novel called Frenchman's Creek, I am powerless to say how it compares with the picture of the same name.
