Shapovalov was born in Tel Aviv, Israel, the son of Tessa and Viktor Shapovalov. His parents were Russian-Israeli citizens. His mother is Jewish, and his father is a Russian Eastern Orthodox Christian. Shapovalov has one sibling, his older brother Evgeniy, who was also born in Israel. The family moved from Israel to Canada before Denis' first birthday. He then lived in Vaughan, Ontario. He started to play tennis at the club where his mother was coaching when he was five years old. His mother Tessa opened her own tennis club in Vaughan, named TessaTennis, to help give him a home base to train and to teach the game to other juniors. She is still his coach, along with Martin Laurendeau. Shapovalov attended Stephen Lewis Secondary School in Vaughan. He plays for Canada, but holds both Israeli and Canadian citizenships.
