Thrill of a Romance (also known as Thrill of a New Romance) is an American Technicolor romance film released by Metro-Goldwyn-Mayer in 1945, starring Van Johnson, Esther Williams and Carleton G. Young, with musical performances by Tommy Dorsey & his Orchestra and opera singer Lauritz Melchior. The film was directed by Richard Thorpe and written by Richard Connell and Gladys Lehman.

The film tells the story of Cynthia Glenn, who, after a whirlwind romance, marries a rich businessman. However, on the first day of their honeymoon, her new husband is called away to Washington, leaving her alone at a resort. During this time, she meets and falls in love with a war hero, Tommy Milvaine, played by Van Johnson.

This was the second of five films that paired Williams and Johnson together. Made over a period of eight years, those that followed were Easy to Wed (1946), Duchess of Idaho (1950) and Easy to Love (1953).

Thrill of a Romance was a box office success, becoming the seventh-highest-grossing film of 1945.
