Laraine Day (born La Raine Johnson, October 13, 1920 – November 10, 2007) was an American actress, radio and television commentator, and former Metro-Goldwyn-Mayer (MGM) contract star.

As a leading lady, she was paired opposite major film stars, including Robert Mitchum, Lana Turner, Cary Grant, Ronald Reagan, Kirk Douglas, and John Wayne.

[3][4] The family later moved to California, where she began her acting career with the Long Beach Players, including her friend and contemporary Robert Mitchum.

[2][5] After a talent scout spotted her with the Long Beach Players, she signed a contract with Goldwyn studios, for which she made her cinematic debut.

[6] Shortly afterwards, she won lead roles at RKO Pictures in several George O'Brien Westerns, in which she was billed as Laraine Johnson.

[7][8] In 1939, she signed with MGM, and became popular and well known (billed as Laraine Day) as Nurse Mary Lamont, the title character's love interest and eventual fiancée in a string of seven Dr. Kildare movies beginning with Calling Dr. Kildare (1939), with Lew Ayres in the title role.

She also starred in the Alfred Hitchcock thriller Foreign Correspondent (1940) with Joel McCrea and the psychological mystery The Locket (1946) with Robert Mitchum, Brian Aherne, and Gene Raymond.

[11] Also in 1941, she was Ronald Reagan's leading lady in the Western comedy The Bad Man, starring top-billed Wallace Beery and Lionel Barrymore.

That same year, she made her stage debut opposite Gregory Peck in the national theater tour of Angel Street.

[18] Day was granted an interlocutory divorce from Hendricks on January 20, 1947, which required her to wait one year before remarrying.

[27] She was a vocal supporter of Richard Nixon, whom she later met at the 1968 Republican National Convention, citing him as the type who would "go out of his way to help the American people".

I consider myself lucky to have been his leading lady in The Bad Man and a short-subject reel and as a nation all together we are beyond fortunate to have the leadership of such fine people as the Reagans.

"[29] In October 1960, Day appeared in the Nixon–Lodge Bumper Sticker Motorcade Campaign in Los Angeles along with Ginger Rogers, Cesar Romero, Irene Dunne, Dick Powell, Mary Pickford, and John Payne.

[32] During World War II, the Royal Canadian Air Force 427 Lion Squadron had been "adopted" by MGM.
