Styrman Karlssons flammor (First Mate Karlsson's Sweethearts) is a 1938 Swedish comedy film directed by Gustaf Edgren. The script was written by Oscar Rydqvist and Oscar Hemberg. It was based on Sigge Strömberg's novels Styrman Karlssons flammor and Styrman Karlssons bröllopsresa, which were published in 1918 and 1919. Edgren had earlier created a silent version of the film, also titled Styrman Karlssons flammor, in 1925. Three actors appeared in both films: Karin Swanström, Knut Lambert, and Nils Whiten. In Denmark, Annelise Reenberg created a Danish version of the same novels in 1958 called Styrmand Karlsen.

The Norwegian actress Nanna Stenersen played the role of Bessie Mathiesen, and another Norwegian actor, Alfred Maurstad, played a minor role as the smuggler Joe.

The film had its Swedish premiere at the Scandia theater in Stockholm on September 19, 1938.
