Mr. and Mrs. North are fictional American amateur detectives. Created by Frances and Richard Lockridge, the couple were featured in a series of twenty-six Mr. and Mrs. North novels, a Broadway play, a motion picture, and several different radio and television series.

Mr. and Mrs. North was a radio mystery series that aired on CBS from 1942 to 1954. Alice Frost and Joseph Curtin had the title roles when the series began in 1942. Publisher Jerry North and his wife Pam lived in Greenwich Village at 24 St. Anne's Flat. They were not professional detectives but simply an ordinary couple who stumbled across a murder or two every week for 12 years. The radio program eventually reached nearly 20 million listeners.

The characters originated in 1930s vignettes written by Richard Lockridge for the New York Sun, and he brought them back for short stories in The New Yorker. These stories were collected in Mr. and Mrs. North (1936). Lockridge increased the readership after he teamed with his wife Frances on a novel, The Norths Meet Murder (1940), launching a series of 26 novels, including Death takes a Bow, Death on the Aisle and The Dishonest Murderer. Their long-run series continued for over two decades and came to an end in 1963 with the death of Frances Lockridge.

In "Married Sleuths," Charles L.P. Silet captured the flavor of the novels: Albert Hackett and Peggy Conklin had the title roles in the Broadway production Mr. and Mrs. North, which ran 163 performances at the Belasco Theatre from January 12, 1941, to May 31, 1941. Alfred De Liagre, Jr. produced and directed the play written by Owen Davis. In that version, the North's apartment is located on Greenwich Place, realized in a scenic design by Jo Mielziner.

The Owen Davis play became a 1942 MGM movie starring Gracie Allen and William Post, Jr. with Millard Mitchell repeating his role of Detective Mullins from the Broadway production. Others in the cast were Paul Kelly, Rose Hobart and Keye Luke.

In 1946, Mr. and Mrs. North received the first Best Radio Drama Edgar Award from the Mystery Writers of America (in a tie with CBS's Ellery Queen).

Also in 1946, producer-director Fred Coe brought the Owen Davis play to television (on New York City's WNBT) with John McQuade and Maxine Stewart in the leads and Don Haggerty, Joan Marlowe and Millard Mitchell repeating their Broadway roles.

Barbara Britton and Richard Denning starred in the TV adaptation seen on CBS from 1952 to 1953 and on NBC in 1954. The series was unusual in that it was Mrs North who solved the cases while Mr North was just background most times. Guest appearances on this series included Raymond Burr, Hans Conried, Mara Corday, Carolyn Jones, Katy Jurado, Jimmy Lydon, Julia Meade, William Schallert and Gloria Talbott. Sixteen episodes of the TV series have been released in the "Best of TV Detectives" box set.

Mr. and Mrs. North were resurrected in spirit with ABC's Hart to Hart, the 1979-84 crime drama about a wealthy husband (Robert Wagner) and wife (Stefanie Powers) who spent as much time solving murders as romancing each other and pursuing careers as an industrialist and a journalist, played the crime theme with wry wit reminiscent of the Norths in their heyday.
