Marta Kostyuk is a Ukrainian professional tennis player, born in 2002, known for her aggressive playing style, excellent baseline movement, and fighting spirit. She burst onto the world stage as a junior prodigy and, in recent years, has established herself among the elite of women's tennis (WTA).

Kostyuk captured the world's attention in 2017 at just 14 years old by winning the Australian Open junior title. The following year, in 2018, she received a wildcard entry into the main draw of the Australian Open and reached the third round, becoming the youngest player to reach that stage of a Grand Slam since 1997.

She broke into the Top 100 in 2020 and the Top 50 in 2021. In 2023, she won her first WTA singles title in Austin, USA, and cracked the world's Top 30.

The year 2024 marked her definitive leap to the top tier; she reached the Australian Open quarterfinals and the finals of major tournaments such as Stuttgart and San Diego, propelling her into the Top 20.

In 2026, she is enjoying the best season of her life: she strung together a spectacular winning streak on clay, won her first major WTA 1000 title in Madrid, reached the semifinals at Roland Garros, made the Wimbledon semifinals for the first time, and achieved a career-high ranking (World No. 12).
