The Beechcraft Super King Air family is part of a line of twin-turboprop aircraft produced by the Beech Aircraft Corporation (now the Beechcraft Division of Hawker Beechcraft). The King Air line comprises a number of model series that fall into two families: the Model 90 series, Model 100 series (these models comprising the King Air family), Model 200 series and Model 300 series. The latter two models were originally marketed as the "Super King Air" family, but the "Super" was dropped in 1996.

The Super King Air family has been in continuous production since 1974, the longest production run of any civilian turboprop aircraft in its class. It has outlasted all of its previous competitors and as of 2007 the only other aircraft in its class is the Piaggio Avanti. As of December 2008, the B200, B200GT and the larger B300 are the production models. Special mission derivative versions of these models are also available for order.
The Beechcraft 1900 regional airliner was derived from the Model 200 King Air.
