Ski Party is a 1965 American teen musical comedy film directed by Alan Rafkin and starring Frankie Avalon, Dwayne Hickman, Deborah Walley and Yvonne Craig. It was released by American International Pictures (AIP). Ski Party is considered as a beach party film spin-off, with a change of setting from the beach to the ski slopes – although the final scene places everyone back at the beach.

Todd Armstrong (Avalon) and Craig Gamble (Hickman) are college undergraduates from California, whose romantic relationships with students Linda Hughes (Walley) and Barbara Norris (Craig) are rocky. Arrogant, handsome, athletic classmate Freddie (Aron Kincaid) has no such problems and chooses not to resist all the women chasing after him. As president of the Ski Club, Freddie organizes a midterm vacation trip to ski country (in Sawtooth National Forest) in Idaho. Although they know nothing about skiing, Todd and Craig follow Linda and Barbara on this bus trip to try to learn "the secret of Freddie's technique".

Once at the rustic ski resort, Todd and Craig pose as frumpy, non-threatening, young English women, Jane and Nora. When not interrupted by a mysterious ice-skating, yodeling polar bear or toying with psychologically imbalanced and lederhosen-clad lodge manager Mr. Pevney (Robert Q. Lewis), they observe the women in their group to learn how they have gone wrong.

To make Linda jealous, Todd attracts the attention of gorgeous, curvy Swedish ski instructor Nita (Bobbi Shaw) when he's dressed as himself. However, Freddie becomes obsessed with Craig when Craig is dressed as a woman, not accustomed to women who play "hard to get". Nita persuades Todd, over Freddie's goading, to compete in a ski jump against Freddie. Todd's jump forces Craig to shoot him down, resulting in a broken leg.

Todd crawls through miles of deep snow late at night with his broken leg covered in a plaster cast, to Nita's house. Toting a bottle, he learns that Nita is not the exotic minx she pretends to be, but aspires to be treated like an "American girl", that is, with much "talk" and little "action".

Back at the lodge, Freddie, still obsessed with Craig's "female" Nora, tries to break down Nora's room door. Stuck inside, Todd and Craig contemplate their next move as they escape through a window. Somehow, they hail a taxi and rack up an enormous fare to Santa Monica, California. Freddie follows on a moped that is piloted by fur-coated lodge manager Pevney. The rest of the group abruptly ends its spring break and follows behind on the bus.

Todd, Linda, Craig, and Barbara arrive, with the rest of the group and Pevney, at Todd's parents' beachfront house. There, the two couples share their true feelings, and the boys surprise the women with their ruse.

Delusional Freddie runs into the Pacific Ocean, calling to his beloved Nora, after Craig tells him that when she heard Freddie was coming, she started swimming: By now, she is "somewhere between here and Japan." Craig encourages Freddie to hurry; maybe he can catch her "somewhere near Guam".
