Love in 3-D (German: Liebe in drei Dimensionen) is a 1973 German adult comedy film directed by Walter Boos. The story features Petra (Ingrid Steeger), a naive 17 year old girl, who rents her sister Dagmar's apartment in Munich, and the sexual escapades of the other residents of the apartment block.

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 as everything from oranges, water, tree branches, swings, and breasts are thrust out toward the audience. One standout (non-adult) sequence involves a spider during a ride in an old ghost house.
