The Irony of Fate, or Enjoy Your Bath! (Russian: Ирония судьбы, или С лёгким паром!, romanized: Ironiya sud'by, ili S lyogkim parom!, literally: The Irony of Fate, or With A Light Steam!), usually shortened to The Irony of Fate, is a 1976 Soviet romantic comedy television film directed by Eldar Ryazanov and starring Andrey Myagkov, Barbara Brylska, Yury Yakovlev and Lyubov Dobrzhanskaya. The screenplay was written by Emil Braginsky and Ryazanov, loosely based on the director's 1971 play, Once on New Year's Eve (Russian: Однажды в новогоднюю ночь).

Filmed at the Mosfilm Studios, The Irony of Fate doubles as a screwball comedy and a love story tinged with sadness. It was one of the most successful Soviet television productions and remains a highly popular New Year's Eve classic in Russia and the post-Soviet states, with millions tuning in to rewatch it every New Year's Eve.
