Siegfried & Roy are two German-American entertainers known for their long running show of illusions in Las Vegas, Nevada, USA.

The duo gave their final performance on February 28, 2009, after a hiatus of over five years.

Their show was famous for including white tigers, and due to their dependence on white tigers for their act, the duo started a tiger-breeding program.

Siegfried Fischbacher and Roy Horn were born and grew up in Germany. They emigrated to the United States and became naturalized citizens.
