Viktória Hrunčáková (née Kužmová; born 11 May 1998) is a Slovak professional tennis player. She has been ranked as high as No. 43 in singles and No. 27 in doubles in the world by the WTA. Hrunčáková has won five doubles titles on the WTA Tour and 26 titles (17 in singles, 9 in doubles) on the ITF Circuit. She also ended runner-up at the Premier-level 2019 St. Petersburg Trophy and at the 2021 Yarra Valley Classic in doubles, along with Anna Kalinskaya. With the Slovakia team, she contributed to achieve for the first time the final for her country at 2024 Billie Jean King Cup, losing only in the final to Italian Lucia Bronzetti.
As a junior, she won the girls' doubles event at the 2015 US Open alongside Aleksandra Pospelova, defeating Kalinskaya and Anastasia Potapova in the final. A year later, she entered final of the 2016 US Open in the girls' singles, where she lost to Kayla Day. She continued her success at majors as a senior, reaching the 2019 US Open semifinal in the women's doubles alongside Aliaksandra Sasnovich, where they lost to Ashleigh Barty and Victoria Azarenka.
Kužmová was born 1998 in Košice to mother Ingrid and father Radovan. Sister Katarína, who is three years younger, followed her into the world of professional tennis, and obtained her WTA first ranking points in 2018. Kužmová was introduced to tennis at age four by her father, who used to run a tennis club.
Kužmová reached a career-high ranking of No. 24 as a junior. She began playing on the ITF Junior Circuit in January 2012 at age 13, and in September of the same year won her first singles and doubles titles at the low-level Grade-5 Mostar Open. The following year, she won the Grade-4 Nazmi Bari Cup in the singles event, and a week later she finished as runner-up in the singles and as champion in the doubles at another Grade-4, the Montenegro Open. During her quarterfinal match at the 2013 Losinj Juniors Cup, against another Slovak player, Nikola Dolakova, she was forced to retire in the second set due to injury. She spent rest of the 2013 season out of tennis.
She returned in early 2014, when she reached her first Grade-2 final in the singles event at the Slovak Junior Indoor. A month later, partnering with Kristína Schmiedlová, she won the doubles title at the Grade-1 Mediterranee Avenir in Casablanca, after being awarded a walkover victory due to the withdrawal of Ioana Ducu and Anna Bondár. Later, again with Schmiedlová, she won another doubles title at the Grade-1 Perin Memorial in Umag. Kužmová made her junior major debut in 2014 at the French Open, reaching only the first round in both the singles and the doubles. Then, she went one round further at Wimbledon, reaching the second round in both the singles and the doubles. At the US Open, she lost in the second round in singles but partnered with Schmiedlová to make her first semifinal at a Grand Slam tournament.
In January 2015, in her debut at the Australian Open, she reached her first major third round in singles, while in doubles, she failed in the first round. Despite an early loss at the French Open in both singles and doubles, Kužmová then reached her first singles major semifinal at Wimbledon, but lost to eventual champion Sofya Zhuk. She also made progress in doubles, winning the 2015 US Open alongside Russian player Aleksandra Pospelova. They defeated Potapova and Kalinskaya on their way to the title. Next year, she failed in defending her US Open doubles title but finished runner-up in singles, losing to Kayla Day. During her junior career, she also won two doubles titles with her younger sister Katarina at the Grade-4 Ziliona Junior Open in August 2015 and 2016.

At the Mallorca Open, she had to qualify and succeeded, before she lost to Polona Hercog in the first round.
