Joseph Coyne was an American-born vaudevillian and musical comedy actor whose career spanned nearly 50 years, from 1883-1931. A popular performer in the U.S., he achieved major stardom in the role of Prince Danilo in George Edwardes' London adaptation of The Merry Widow, which led to other leading roles in Edwardian musical comedy and many other productions in London, New York, and Australia.

The Merry Widow is an operetta by the Austro-Hungarian composer Franz Lehár. The librettists, Viktor Léon and Leo Stein, based the story – concerning a rich widow, and her countrymen's attempt to keep her money in the principality by finding her the right husband – on an 1861 comedy play, L'attaché d'ambassade by Henri Meilhac.
