This list of Donald Duck universe characters focuses on Disney cartoon characters who typically appear with Donald Duck and Scrooge McDuck, but are not related to them. For relatives of Donald and Scrooge, see Duck family (Disney) or Clan McDuck. For characters exclusive to the DuckTales franchise, see List of DuckTales characters.

Ducks are the most common type of named characters in the Donald Duck universe. Like Donald, they appear as white American Pekin ducks. This section contains a list of characters with the surname "Duck" who are not related to Donald. As Don Rosa explained, "Duck" is an common name in Duckburg (just as "Smith" or "Jones" are common in the real-life United States) and does not necessarily identify a blood relation of Donald.

Umperio Bogarto is a private detective. He was invented by Carlo Chendi and Giorgio Cavazzano in the early 1980s to be used as a supporting character in two stories with O.K. Quack. But ironically Bogarto became more popular than O.K. himself. He is named after the actor Humphrey Bogart. Bogarto's office is straight from a typical 1920s-era American detective novel. He is running severely late on payment of his rent. Bogarto wears a trench coat, a fedora and gum-soled shoes.

As a detective, Bogarto is rather clumsy and incompetent. Despite this, Scrooge McDuck often relies on his services, because he is by far the cheapest detective in Duckburg. Bogarto started his career as a hotel detective, with the job of looking for clients who left without paying. After moving on to bigger cases, Bogarto has started cooperating with Fethry Duck.
