"By Strauss" is a 1936 song composed by George Gershwin, with lyrics by Ira Gershwin.
Performed by the Gershwins at private parties, Vincente Minnelli included it in his 1936 revue The Show is On, where it was introduced by Gracie Barrie and Robert Shafter. It was then performed by Gene Kelly and Oscar Levant in Minnelli's 1951 film An American in Paris. The song was also featured in the musical Nice Work If You Can Get It, performed by the character Estonia Dulworth in a counterpoint with a reprise of "Sweet and Lowdown".
