The Slippery Noodle Inn is a large blues bar and restaurant with two performance stages in downtown Indianapolis, Indiana.

It also has the distinction of being the oldest continuously operating bar in the state of Indiana,[3] having opened in 1850 as the Tremont House.

The Inn served as a stop on the Underground Railroad during the American Civil War.

During prohibition it was called a restaurant, although beer was still being made in the basement, and later it housed a brothel until 1953.

Its tin ceiling dates to 1890 and the oak bar is also over a century old.
