"The Day of Black Sun" is the tenth and eleventh episodes of the third season of the American animated television series Avatar: The Last Airbender, and the 50th and the 51st episode overall. The show follows Aang (Zach Tyler Eisen), the last airbender and the “Avatar”, on his journey to bring balance to a war-torn world by mastering all four elements: air, water, earth, and fire. On his quest, he is joined by companions Katara (Mae Whitman), Sokka (Jack DeSena), and Toph Beifong (Jessie Flower). The season also follows Zuko (Dante Basco) as he returns to the Fire Nation only to face his conflicting feelings about his part in the war. The episodes have the sub-titles "The Invasion" and "The Eclipse" respectively.

The second part was directed by Joaquim Dos Santos and written by head writer Aaron Ehasz, following the beginning of the eclipse, and Zuko standing up to his father Fire Lord Ozai (Mark Hamill).
