Maria Timofeeva defeated Kateryna Baindl in the final, 6–3, 3–6, 6–0 to win the singles tennis title at the 2023 Budapest Grand Prix.

Timofeeva won the title both as a lucky loser and in her first main-draw appearance on the WTA Tour.

She thus became the first lucky loser to win a WTA Tour singles title since Coco Gauff in 2019 (and only the fourth player overall), and the first player to win a title on her tour debut since Angelique Widjaja in 2001.
