Private Lives is a 1930 comedy of manners in three acts by Noël Coward. It concerns a divorced couple who, while honeymooning with their new spouses, discover that they are staying in adjacent rooms at the same hotel. Despite a perpetually stormy relationship, they realise that they still have feelings for each other. Its second act love scene was nearly censored in Britain as too risqué. Coward wrote one of his most popular songs, "Some Day I'll Find You", for the play.

Sir Noël Peirce Coward was an English playwright, composer, director, actor, and singer, known for his wit, flamboyance, and what Time magazine called "a sense of personal style, a combination of cheek and chic, pose and poise".
