"Chicago" is a popular song written by Fred Fisher and published in 1922. The original sheet music variously spelled the title "Todd'ling" or "Toddling." The song has been recorded by many artists, but the best-known versions are by Frank Sinatra, Ben Selvin and Judy Garland. The song alludes to the city's colorful past, feigning "... the surprise of my life / I saw a man dancing with his own wife", mentioning evangelist Billy Sunday as having not been able to "shut down" the city, and State Street where "they do things they don't do on Broadway".

Fred Fisher was a German-born American songwriter and Tin Pan Alley music publisher.
