Problem Child 3: Junior in Love (known onscreen as simply Problem Child 3) is a 1995 American black comedy television film directed by Greg Beeman and written by Michael Hitchcock. It is the third and final installment of the Problem Child trilogy created by Scott Alexander and Larry Karaszewski. The film premiered on NBC on May 13, 1995. It is the only film in the series not to receive a theatrical release.

In the film, Junior, now a preteen, is infatuated with a girl named Tiffany, but she does not notice him. Things take a mischievous turn when he finds out there are three other boys interested in her as well. Junior himself is portrayed by Justin Chapman replacing Michael Oliver and Ben is portrayed by William Katt replacing John Ritter. Neither Annie (Amy Yasbeck) nor Trixie (Ivyann Schwan) appear in it, nor are they mentioned. Gilbert Gottfried and Jack Warden are the only cast members to appear in all three films (with Gottfried being the only one appearing in the films and the animated series). Eric Edwards reprises his role as "Murph" from the second film. The film neither explains why Junior is once again wearing a bow-tie, since he discarded it at the end of the first film, nor how Big Ben is still rich, since his apparent new wife, LaWanda Dumore, is never mentioned.
