Pork Tenderloin Internal Temp: Is It Supposed to Be Pink?

Yes, a little pink is fine

Pork tenderloin is done and safe at 145°F internal followed by a 3-minute rest, and meat at that temperature commonly still shows a faint pink color in the center. That is not undercooked pork; it is what a properly cooked, juicy tenderloin looks like. The rest is part of the standard: the internal temperature holds or keeps climbing for those minutes off the heat, which is where the last of the safety margin comes from. The old advice to cook all pork to well done and gray came from trichinosis concerns that modern pork production has essentially eliminated, and food safety guidance has reflected that for years.

Why tenderloin cooks so much faster than other cuts

Tenderloin is a small, lean, single-muscle cut with none of the connective tissue that makes brisket or pork butt need hours to break down. There is nothing to render, so cooking it past 145°F only dries it out; there is no tenderness reward waiting at a higher temperature the way there is with brisket.

Pit temperature and timing

Smoke at 250°F, a bit hotter than the 225 to 250°F range used for bigger cuts, since tenderloin is thin enough that it does not need the low end of that range. It typically takes just 1.5 to 2 hours, among the fastest cooks of any classic smoker cut, alongside smoked sausage.

Wood and rest

Apple or cherry are the standard pairing, mild woods that will not overpower a lean, delicate cut the way a stronger wood could. Rest tenderloin about 10 minutes before slicing, enough to let juices settle without needing anywhere near the rest time of a bigger cut.
