Gjergj Arianiti (1383–1462) was an Albanian feudal lord who led several successful campaigns against the Ottoman Empire. He was the father of Donika, Skanderbeg's wife, as well as the grand-uncle of Moisi Arianit Golemi. Gjergj Arianiti was Skanderbeg's ally within League of Lezhë before abandoneding the alliance after the defeat in Berat in 1450. He later returned. Robert Elsie emphasizes that Arianiti was often Skanderbeg's rival. He allied with the Kingdom of Naples in 1446, left his alliance with Skanderbeg by 1449 and allied with Venice in 1456. However his daughter married Skanderbeg and he remained officially part of the League of Lezhe, continuing to fight Ottomans successfully up to his death in 1462.

Donika Arianiti, also known as Donika Kastrioti, was an Albanian noblewoman and the spouse of Albanian leader and national hero Skanderbeg. She was the daughter of Gjergj Arianiti, an earlier leader in the ongoing revolt against the Ottomans.
