''Hart to Hart'' was an American television series that ran from 1979 to 1984 on Creator/{{ABC}}. It starred Robert Wagner and Stefanie Powers and was produced by Creator/AaronSpelling.

The show focused on Jonathan Hart (Robert Wagner), a rich CEO, and his wife Jennifer (Stefanie Powers), a freelance journalist. In their spare time, the two pair up as amateur detectives, with some help from their butler Max (Lionel Stander). Each episode focused on a crime that they were currently trying to solve. Most of the cases they worked on dealt with murder, robbery, kidnapping, and espionage.

After five seasons on the air, the show was canceled due to low ratings in the last season. In 1993, the cast reunited to make eight made-for-TV movies.
!!This show provides examples of:
* AmateurSleuth: Jonathan and Jennifer.
* DontTellMama: A ValentinesDayEpisode had the Harts tangle with a diamond smuggling ring operating out of a gourmet chocolate shop. The head of the group is the son of Mrs. Bittersweet, the woman who runs the chocolate shop, and he's frequently covering up the smuggling ring's activities from her. [[spoiler: She's actually the real head of the ring, and those cover-ups were her son trying not to disappoint her with his blunders.]]
* EarlyInstallmentWeirdness: In the first season, Max's opening-credits narration ended with the phrase: "I take care of them, which ain't easy, because their hobby is ... murder!" As the show isn't actually about happily married serial killers, subsequent seasons modified this to "...because when they met, it was murder!"
* FourthDateMarriage: The flashback episode "Two Harts Are Better Than One" shows that Jonathan and Jennifer only knew each other for a few days in London before he proposed.
* HappilyMarried: The Harts are so much this trope that one episode revealed three associates of Jonathan established a betting pool on the night of his bachelor party, wherein they wagered cash on how long the Harts would remain married. One guy, who bet they'd stay together for five years but split before ten, took it upon himself to make it look like Jonathan was cheating on Jennifer to split them up. Every attempt to sow marital discord failed miserably, but the Harts decided to pretend they were splitting up to figure out who was going to all this trouble. Jennifer never believed for a second that Jonathan would ever think of betraying her.
* GenreBlindness: A lot of episodes are about the Website/{{Badass of the Week}} trying to outsmart the Harts but they seem to never have heard of all the other bad guys crossing the Harts' way whose successes were questionable.
* IdleRich: They are when they aren't solving crimes.
* MadeForTVMovie: Eight of them.
* Magazine/{{MAD}}: ''Har To Har''
* MysteryMagnet
* MysteryOfTheWeek
* OneHourWorkWeek: Though Jonathan is the CEO of a very large company, he seems to spend plenty of time solving crimes.
* PrettyInMink: Jennifer often wore a fur when they went to a special event.
* SpiritualAdaptation: The show is basically TheThinMan with the gender roles reversed.
* StalkerWithACrush: A recurring plot point. Either Jonathan and Jennifer would attract one of these.
* WheelProgram: NBC attempted to use the 1993 reunion movies as an anchor for a new ''Friday Night Mystery Movie'' series, [[FridayNightDeathSlot but the idea didn't take off.]]
* YouLookFamiliar: Both Stefanie Powers and Lionel Stander co-starred in separate episodes of Wagner's earlier series ''Series/ItTakesAThief1968''.
