Marriage Lines is a British television sitcom first broadcast between 1963 and 1966. The series gave Richard Briers and Prunella Scales, its lead stars, a significant boost in their careers. At first titled The Marriage Lines, the programme was written by Richard Waring, and was later adapted for radio.

When Richard Waring was writing Marriage Lines, he had Richard Briers in mind, and also worked with him on Brothers in Law. Graeme Muir, the producer of Marriage Lines, also worked on Brothers in Law. In early episodes, The Marriage Lines was subtitled A Quizzical Look at the Early Days of Married Life.

George and Kate Starling are a newly married couple, and the comedy comes from many ordinary domestic situations. George is a junior clerk in an office and wants the public house camaraderie of the single man in his office, while Kate gets increasingly frustrated by her domestic duties. In the third series, Kate gives birth to a daughter, Helen. The last episode of the fourth series, "Goodbye George – Goodbye Kate", shows the couple going to live in Lagos, Nigeria because of George's job. This was meant to be the last episode, however a fifth series was commissioned. The Starlings return to England as Kate is pregnant again, and gives birth in the final episode.

All episodes are 25 minutes, except the fifth series, when the episodes are 30 minutes long. Many episodes are missing from the television archives.
