What is the name of the Muppet bear who wears a hat and bow tie?

The Muppet bear who wears a hat and bow tie is Fozzie Bear.

Fozzie is a comedian whose confidence regularly exceeds his talent. He performs deliberately corny jokes, often punctuating them with his familiar “Wocka wocka!” catchphrase. His routines frequently receive groans from the audience, especially Statler and Waldorf, but Fozzie remains determined to entertain.

The character is closely associated with The Muppet Show, where he performs stand-up routines and shares a particularly strong friendship with Kermit the Frog. Fozzie's orange-brown appearance, brown pork-pie-style hat and spotted necktie give him a distinctive stage look. His name also plays on “foz,” a term connected with a clumsy or awkward person.

Frank Oz performed Fozzie for most of the character's classic era, helping define his nasal voice and anxious comic personality. Fozzie is sometimes mistaken for simply being a version of a generic teddy bear, but he is specifically written as a struggling professional comedian. His recurring failure is part of the joke: unlike a polished entertainer, Fozzie keeps returning to the stage regardless of the reaction.
