Fiordaliza Cofil (born 27 October 2000) is an athlete from the Dominican Republic, of a Haitian background, who competes as a sprinter. She won the gold medal in the mixed 4 × 400 metres relay at the 2022 World Athletics Championships. Cofil holds Dominican Republic records in the 100 metres, as well as the women's and mixed 4 × 400 m relay.

At the 2022 World Championships in Eugene, Oregon, Cofil ran the anchor leg of the mixed 4 × 400 m relay and chased down American Kennedy Simon to clinch only the third ever gold medal at the Games for her country (alongside Lidio Andrés Feliz, Marileidy Paulino and Alexander Ogando).

In 2023 World Athletics disqualified her from competing at the 2023 World Athletics Championships in Budapest under the DSD Rules due to naturally occurring high levels of testosterone. She underwent medical treatment to lower her levels and returned in 2024 in the 100 and 200 metres.

She ran as part of the 4 × 100 m relay team at the 2024 World Relays Championships in Nassau, Bahamas.
