"Love and Marriage" is a 1955 song with lyrics by Sammy Cahn and music by Jimmy Van Heusen. It was introduced and popularized by Frank Sinatra, whose recording reached #5 on the Billboard chart and #3 on the UK singles chart.

"Love and Marriage" was introduced by Frank Sinatra in the 1955 television production of Thornton Wilder's Our Town, which aired on Producers' Showcase. Sinatra went on to record two versions of the song. The first was recorded for Capitol Records on August 15, 1955, and became a major chart hit. (A competing version by Dinah Shore also achieved popularity.) This first recording appeared on the 1956 album This Is Sinatra! The second version was recorded for the Reprise Records album A Man and His Music on October 11, 1965. The Capitol version was later used as the theme song for the 1987–1997 Fox TV sitcom Married... with Children.

Although both versions were arranged by Nelson Riddle, there are many slight but noticeable differences. For instance:

As part of Producers' Showcase, "Love and Marriage" won the 1956 Emmy Award for Best Musical Contribution.
