"Love and Marriage" is a song with lyrics by Sammy Cahn and music by Jimmy Van Heusen.

It was introduced by Frank Sinatra in the 1955 television production Our Town that aired on Producers' Showcase. He went on to have a major 1955 chart hit with it. A competing version by Dinah Shore also achieved popularity.

The Sinatra version was later used as the theme song for the long-running sitcom Married... with Children.
