What is the name of the taco filled with stewed chicken in a tomato-chipotle sauce?

The taco filled with stewed chicken in tomato-chipotle sauce is called tacos de tinga. Tinga is a Mexican preparation of shredded meat—especially chicken—cooked with tomatoes, chipotle chiles in adobo, and sliced onions.

The dish is strongly associated with Puebla and central Mexico, although it is now eaten widely across the country and internationally. The earliest known published recipe for tinga appears in the 1881 cookbook La cocinera poblana, making it a documented nineteenth-century dish.

Tinga is commonly served on tostadas, tacos, and other masa-based foods. Typical accompaniments include refried beans, avocado, crumbled cheese, Mexican crema, salsa, or lettuce. Recipes can vary: pork, beef, fish, mushrooms, and other vegetables may replace chicken. That flexibility explains why “tinga” identifies the saucy preparation more than one fixed ingredient. Mole, adobo, and pipián are different sauces or preparations, not the canonical name for this taco.
