An Angus burger is a hamburger made using beef from Angus cattle. The name Angus burger is used by several fast-food hamburger chains for one or more "premium" burgers; however, it does not belong to any single company. Pre-made frozen Angus burgers are increasingly available from retailers.

Burger King (Hungry Jack's) is believed to have been the first major fast-food burger chain to introduce an Angus burger.
Since 2006, McDonald's has test-marketed its own version of the sandwich in several markets, including Chicago, Illinois and upstate New York. The test sandwich was offered in three varieties that had similar makeup of the standard Burger King version, the mushroom Swiss and the bacon cheese.
In Canada, the hamburger chain Harvey's sells an Angus burger on its menu, while McDonald's Canada introduced an Angus burger in May 2008.
In mid-2009, two varieties of the Angus burger were added to McDonald's Australia and New Zealand menus. The first is the "Grand Angus", which consists of Angus beef, mustard, McChicken-sauce mayonnaise, processed cheese, red onion, salad and tomato. The second is the "Mighty Angus", which consists of Angus beef, processed cheese, McChicken sauce, onion relish, red onion and bacon. In December 2015, the Grand Angus was re-released as the Classic Angus and the Mighty Angus was re-released as the Aussie BBQ Angus.
In November 2011, McDonald's began selling the Angus burger in Brazil in two variations: Angus Deluxe and Angus Bacon.
