Duck Dynasty is an American reality television series that aired on A&E from 2012 to 2017. The series portrays the lives of the Robertson family, who became successful from their family-operated business, Duck Commander. The West Monroe, Louisiana business makes products for duck hunters, primarily a duck call called Duck Commander. The episodes are structured in a sitcom story format, unlike other reality television series, which has allowed it to have continued success in syndication. The bearded Robertsons – brothers Phil and Si, and Phil's sons Jase, Willie, and Jep – are the poster characters for the show, though the main cast consists of family and friends of the Robertsons such as their wives – Miss Kay, Korie, Missy Robertson, and Jessica Robertson – as well as coworkers Martin and Godwin, beardless brother Alan, radio host Mountain Man, and the Robertson kids – Sadie, John Luke, Bella, Willie Jr, Mia, Reed, and others. The family was previously featured on the Duckmen series, and Outdoor Channel's Benelli Presents Duck Commander and its Buck Commander spin-off.

The 2013 fourth-season premiere "Till Duck Do Us Part" drew 11.8 million viewers; the most-watched nonfiction cable series in history, and with a 5.0 rating it is the highest rated telecast for A&E. The show earned $80 million in advertising sales for the first nine months of 2013, and merchandise has generated another $400 million in revenue. After 11 seasons, the series concluded on March 29, 2017, with the hour-long finale "End of an Era", the episode concluded with Si Robertson performing the show's theme song "Sharp Dressed Man" alongside ZZ Top.

Duck Dynasty has launched several spin-off series since its release, including Jep & Jessica: Growing the Dynasty and Going Si-Ral during the show's success on A&E. Following the show's conclusion, Blaze Media produced the 2017-2021 show In the Woods with Phil, and starting in 2022 Fox Entertainment created a streaming and broadcast syndication series called Duck Family Treasure. Like past shows, many Robertson family members, co-workers, and friends appear in these spin-offs. Various on-going podcasts continue to prominently feature the Robertsons as well: Phil, Jase, and Alan host Unashamed; Sadie hosts WHOA That's Good Podcast; and Duck Commander produces Duck Call Room with Si, Martin, and Godwin. Outdoor Channel acquired rerun rights to Duck Dynasty in 2016. In 2020 Fox Nation acquired the streaming rights to the show for the year, after that deal concluded Hulu began streaming the series in 2023.
