Leta Lestrange is a character in JK Rowling's Fantastic Beasts and Where to Find Them. She was once a friend of Newt Scamander and is currently engaged to his brother, Theseus. Leta is portrayed by Zoe Kravitz.
Leta comes from the Lestrange family, a family infamously known for mastering in the Dark Arts. She was the half-sister of Corvus Lestrange, whom she felt guilty for abandoning, as the baby drowned when she was a child. Leta was once a friend of Newton "Newt" Scamander. One of her experiments endangered the life of another student, and Newt took the blame. Despite their animosity, Newt kept a photo of Leta with him. Leta eventually began to work at the British Ministry of Magic and became engaged to Newt's brother, Theseus.
