Sons of the Desert is a 1933 American pre-Code comedy film starring Laurel and Hardy. Directed by William A. Seiter, it was released in the United States on December 29, 1933. In the United Kingdom, the film was originally released under the title Fraternally Yours.

In 2012, the film was deemed "culturally, historically, or aesthetically significant" by the United States Library of Congress and selected for preservation in the National Film Registry.

Mr. Laurel and Mr. Hardy belong to a fraternal lodge called Sons of the Desert. It is resolved that all members must attend the upcoming national convention in Chicago. While Oliver is eager to honor the oath no matter what his wife Lottie says, Stan is apprehensive that his own wife Betty won't allow it.

Upon return home, it is then revealed that Mrs. Hardy is vehemently against Oliver attending the convention as she has already planned a retreat to the mountains. To get out of it, Oliver pretends to be ill. Stan then arranges for a fake doctor (a vetenarian) to prescribe a trip to Honolulu. Laurel and Hardy leave for their trip, with their wives unaware that they're really going to the convention.

The boys have a wonderful time at their stag function, though Oliver almost bungles it when fellow conventioneer Charlie has him talk with his sister - Lottie Hardy - by phone. Little do they know that the ship returning from Honolulu is sinking in a typhoon. The wives become alarmed and go to the steamship office, where a list of casualties will be announced later. The wives go to a movie to pass the time until the report comes in -- and see their husbands in a newsreel covering the Sons of the Desert convention. Meanwhile Stan and Oliver return home to find their houses empty. They hide in the attic, but make so much noise that they have to escape from the house before the wives find them. A suspicious policeman turns them in at Hardy's front door.

Under pressure, Oliver tries to maintain the illusion that they were shipwreck survivors, but Betty quickly sees through the lie. Stan eventually confesses, which leads to relief from Betty and anger from Lottie. Betty is pleased to have won her earlier bet with Lottie about which husband was more honest, and rewards Stan with affection. Oliver, however, must face Lottie's fury, not only for the deception but also for embarrassing her in front of her friend.

Sons of the Desert opened at Arthur Mayer's Rialto Theater in New York, usually a haven for horror pictures but always receptive to each new Laurel and Hardy comedy. A Motion Picture Herald reviewer was there: "At the Rialto theatre on Broadway in New York, the audience gave considerable and repeated evidence of definite enjoyment, chuckling at frequent intervals, laughing heartily on occasion. Slapstick comedy laughs there are aplenty, to judge by the Rialto audience." A reporter from the New York Herald Tribune attended the same screening and noticed that the Rialto "was crowded with ecstatic delegates who showed every sign of regarding themselves as being in an ideal world where there were two Chaplins working in one film." Film Daily commented, "This Hal Roach production is more than just an elongated two-reeler [short subject]. It is typical Laurel and Hardy tomfoolery, of course, but with a plot that sustains interest very nicely to the finish. And for the who want laughs, it is a generous feast."Motion Picture Daily covered the Hollywood preview and gave special credit to "William A. Seiter getting the most directorially out of a well constructed story. Seiter has the faculty of building up to a gag, giving it plenty, then letting down just long enough to deliver the next jolt."

Theater owners reported very good business. "A wow at the box-office. People flocked to see these two." (B. R. McLendon, Idabel, Oklahoma); "Well, the boys have done it, and I did not think they could. This latest of theirs is a knockout comedy. Better than ordinary business and that is saying something." (A. E. Hancock, Columbia City, Indiana); "The best feature from this team. It went over big here, as nearly everyone likes that kind of show." (Gladys E. McArdle, Lebanon, Kansas); "Best Laurel and Hardy to date. More story than usual and not so many repeats on the same gag." (C. M. Hartman, Carnegie, Oklahoma).
