Pork tenderloin, also calledpork fillet,^[1]pork steak^[2] orGentleman's Cut, is a long, thin cut ofpork.

As with all (mammalian)quadrupeds, the tenderloin refers to thepsoas major muscle^[3] along the central spine portion, ventral to the lumbar vertebrae, the most tender part of the animal, because those muscles are used for posture rather than locomotion.

In some countries, such as the United States and the Netherlands ('varkenshaas'), pork tenderloin can be bought as a processed product, already flavored with amarinade. A regional dish of theMidwestern United States is apork tenderloin sandwich,^[4] also called a tenderloin – a very thinly sliced piece of pork, which is the larger, tougher loineye - or longissimus - muscle, which is battered or breaded, deep fried, and served on a small bun,^[4] often with garnishes such as mustard, pickle and onions. This sandwich is relatively common and popular in the U.S. Midwest, especially in the states ofIowa andIndiana.^[5] In the southern states, tenderloin is often prepared as a breakfast biscuit, typically with egg or cheese.^{[citation needed]} It is quite common for pork tenderloin to be used as an alternative to beef tenderloin^{[according to whom?]} as it can be just as tender but costs significantly less.

Alton Brown's television showGood Eats includes an episode titled "Tender is the Pork" about pork tenderloin.^[6]
