In the American, French, German, Brazilian, and Korean systems of primal beef cuts, the tenderloin is a cut from the loin, which is located towards the back of the cow, nestled under the ribs, next to the backbone. It spans two primal cuts: the short loin and the sirloin.

The tenderloin is one of the most tender cuts of beef as it comes from a muscle that doesn't get much exercise. It is also one of the most highly prized and correspondingly expensive cuts of beef, due to its tenderness and flavor. Given the tenderness of this cut, the tenderloin is often cooked quickly over high heat, with methods such as grilling or broiling.
