Zacharias Smith (b. 1979/1981) was a student at Hogwarts School of Witchcraft and Wizardry who was sorted into Hufflepuff House. He was a Chaser on the Hufflepuff Quidditch team and a member of Dumbledore's Army, an organisation taught and led by Harry Potter. In 1998 he abandoned the D.A. instead of fighting with them during the Battle of Hogwarts. Ronald Weasley disliked him as soon as they met; mostly because of his attitude while talking to the trio and his disloyalty to Harry Potter and Hogwarts.
