Queer Duck is an American animated web series produced by Icebox Animation (alongside Mondo Media) that originally appeared on the company's website, then later moved to the American cable network Showtime, where it aired following the American version of Queer as Folk. Although far from featuring the first gay cartoon character, Queer Duck was among the first animated series to have homosexuality as its predominant theme.

Like several later television cartoons, Queer Duck was animated in Macromedia Flash. The show was created, written, and executive-produced by Mike Reiss, who also produced network cartoons The Simpsons and The Critic. Queer Duck animation was directed and designed by Xeth Feinberg, in an attempt to be very similar to the animation style of Rocky and Bullwinkle; the theme song was performed by drag celebrity RuPaul. In Canada, Queer Duck aired on Teletoon at Night whilst in the UK it was aired as a short segment as part of magazine show That Gay Show which aired on BBC Choice, the forerunner to BBC Three.

Scholar Lawrence La Fountain-Stokes called the use of the term queer duck as "interesting" and described the show as about a "group of American gay animals" with their personalities seemingly "based on gay white men."

The title character, whose full name is Adam Seymour Duckstein (voiced by Jim J. Bullock), is a gay anthropomorphic duck who works as a nurse. In an interview included on the DVD release of Queer Duck: The Movie, Reiss states that Bullock is the only member of the cast that is actually gay, and that he had insisted that the character be voiced by someone gay.

Queer Duck has cyan-colored feathers, a little spiky fringe, and may wear purple eye shadow. He wears a sleeveless rainbow top and, like almost everyone else in the series, does not wear trousers. This follows the tradition of semi-nudity of cartoon animals exemplified by Porky Pig, Donald Duck, Top Cat, etc. He is often shown to have two fingers and one thumb on each hand, though on occasion he has the three fingers and one thumb per hand that is typical of many contemporary cartoons.

Queer Duck is known to gossip about anything and everything, especially on the phone while watching television, as shown on "Oh Christ!", "The Gaining of Herpes from Sparky" and "A Gay Outing". He is promiscuous in his own way, but not as obsessed with sex as his boyfriend Openly Gator; for example, he'll often utter the word "cock" but swiftly follows it with another word, like "tails", such as in "The Gay Road to Morocco".

His nemesis is known to be radio show host Laura Schlessinger, who is pictured as a haggard and ugly old woman.

Queer Duck has also been a victim of gay bashing, as shown in "Ku Klux Klan & Ollie", in which Ku Klux Klan members attempt to burn his house down. When his disguise fails, he kisses the unveiled Jerry Falwell, only to get shot down by the other homophobes. When in heaven he finds out that famous icons like Socrates and Leonardo da Vinci are also gay, much to the chagrin of Jerry Falwell.
