Junior is a 1994 American comedy film directed and produced by Ivan Reitman, and starring Arnold Schwarzenegger, Danny DeVito and Emma Thompson. The film follows Alex Hesse, an Austrian-American scientist who agrees to undergo a male pregnancy from a newly developed drug Expectane.

The film was released in the United States the day before Thanksgiving on November 23, 1994, to mixed reception and did not match the box office performance of Reitman's earlier films starring Schwarzenegger: 1988's Twins, which also starred DeVito and Schwarzenegger as a comedic duo, and 1990's Kindergarten Cop. Schwarzenegger and Thompson received Golden Globe Award nominations for their performances. The film's theme song, Patty Smyth's "Look What Love Has Done" was also recognized, going on to be nominated for the Academy Award for Best Original Song.
