Laraine Day (October 13, 1920 – November 10, 2007) was an American actress and a former MGM contract star.
 
Day's first marriage was to singer turned airport executive, James Ray Hendricks in 1942. The couple adopted three children:

Christopher, Angela and Michelle. Day filed for divorce from Hendricks in December 1946. Day was granted an interlocutory divorce from Hendricks on January 20, 1947, which required her to wait one year before remarrying.

On January 21, 1947, Day traveled to Juarez, Mexico where she received a second divorce decree. Later that day, she traveled to El Paso, Texas, where she married baseball managerLeo Durocher. Upon returning to California, the judge who granted Day's interlocutory divorce from Hendricks stated that the Mexican divorce she received was not legal and, since she failed to wait the one year period for her divorce to become final, deemed her Texas marriage illegal as well. After waiting approximately one year, Day and Durocher remarried on February 16, 1948, in Santa Monica, California. During her marriage to Durocher, Day was often referred to as "The First Lady of Baseball". While Durocher was managing the New York Giants, she wrote, Day With the Giants.(1952). In 1952, she wrote and published another book entitled The America We Love. She was also the host of Day With the Giants, a 15-minute television interview program broadcast before New York Giants home games. Day and Durocher divorced in June 1960.

On March 7, 1961, Day married television producer Michael Grilikhes. She and Grilikhes had two daughters, Dana Laraine (born November 13, 1962) and Gigi (born October 6, 1964). After their births, Day rarely appeared in films, and only occasionally appeared on TV, usually portraying matronly types.
