The 5th Wheel is an American dating reality television series that aired in syndication from September 17, 2001, to May 21, 2004. The show was initially hosted by comedian Aisha Tyler, but when Tyler left after completing the first season, the remaining two seasons were hosted in narration by announcer Tom Gottlieb.

The series' closing slogan was, "...where strangers become friends, friends become lovers, and lovers become bitter, suicidal exes all on the same show." However, when Gottlieb took over the show, the catchphrase was altered accordingly to say "...where strangers become lovers and lovers become bitter suicidal exes all in the same show."
