Love in 3-D (German: Liebe in drei Dimensionen) is a 1973 German adult comedy film directed by Walter Boos.

The film was dubbed into English for American audiences. As compared to other mid-1970s adult films that were shot in 3-D, Love in 3-D stands out for several reasons. It was shot on 70 mm, very unusual for a low budget adult film. The movie itself contains several notable 3-D scenes which show everything from oranges, water, tree branches, swings, and breasts thrust out toward the audience. One standout (non-adult) sequence involves a spider during a ride in an old ghost house.
