The Pashalik of Yanina, sometimes referred to as the Pashalik of Ioannina or Pashalik of Janina, was an autonomous pashalik within the Ottoman Empire between 1787 and 1822 covering large areas of Albania, Greece, and North Macedonia. Under the Ottoman Albanian ruler Ali Pasha, the pashalik acquired a high degree of autonomy and even managed to stay de facto independent, though this was never officially recognized by the Ottoman Empire. Conceiving his territory in increasingly independent terms, Ali Pasha's correspondence and foreign Western correspondence frequently refer to the territories under Ali's control as Albania.

The capital of the Pashalik was Ioannina, which along with Tepelena were Ali's headquarters. At its peak, Ali Pasha and his sons ruled over southern and central Albania, the majority of mainland Greece, including Epirus, Thessaly, West Macedonia, western Central Macedonia, Continental Greece (excluding Attica), and the Peloponnese, and parts of southwestern North Macedonia around Ohrid and Manastir. The subject population of Ali's domains was quite heterogeneous, including Albanians, Aromanians, Bulgarians, Greeks, Jews, Roma, Serbs, and Turks. Greeks were the most numerous ethnic group,while Orthodox Christians were the most numerous religious group, followed by Muslims.
