Antonio Pastor was an American impresario, variety performer and theatre owner who became one of the founding forces behind American vaudeville in the mid-to-late-nineteenth century. He was sometimes referred to as the "Dean of Vaudeville". The strongest elements of his entertainments were an almost-jingoistic brand of United States patriotism and a strong commitment to attracting a "mixed-gender" audience, the latter being something revolutionary in the male-oriented variety halls of the mid-century. Although he was a performer and producer, Pastor is best known for "cleaning up" bawdy variety acts and presenting a clean and family-friendly genre called vaudeville.

Vaudeville is a theatrical genre of variety entertainment which began in France at the end of the 19th century. A vaudeville was originally a comedy without psychological or moral intentions, based on a comical situation: a dramatic composition or light poetry, interspersed with songs or ballets. It became popular in the United States and Canada from the early 1880s until the early 1930s, while changing over time.
