Hyuna Park is a pianist, composer and bandleader from South Korea who is based in New York City. Her Hangul name is not published in any source found. She grew up in Masan, a port city on the southeast coast of Korea (now part of Changwon), where her mother ran a music school. Her only date of birth in print is the October 4, 1984 listed on her All About Jazz page, which gives no source for it, and no source names her birthplace city. Her own Jazz Generation interview and the Discogs profile ("Korean-born jazz pianist living in New York City") place her Korean upbringing and her New York base beyond doubt.

She says her mother's music school was her main influence. She began on classical piano, then started improvising, and she first heard jazz only after she graduated from high school. Told by everyone she met to go to New York, she moved there and studied jazz for two years at Queens College, learning English at the same time. She has said that getting into the swing feel was the hardest part and still is. No source gives her years at Queens College, her degree or her teachers, and no source describes a performing career in Korea before she left, so her documented Korean basis is her birth and upbringing, her music school childhood and her later Korean-community connections in New York.

In 2018 she formed a trio with the bassist Myles Sloniker and the drummer Peter Traunmueller, whom All About Jazz describes as a Colorado bassist and an Austrian drummer. That year she won the International Women in Jazz festival and the Jimmy Heath Award, according to her biographies. In her own account she was placed in a category with vocalists, and the judges liked her version of "The Boy From Ipanema," which she played with her trio at the 2018 festival. The trio recorded her debut album, Her Morning Waltz, on March 26, 2018 at Douglass Street Recording Studio in Brooklyn, with Amadis Dunkel producing, mixing and mastering. Discogs dates the CD 2018; her Bandcamp page gives a release date of March 20, 2019, and Apple Music dates it April 1, 2019.

Korean Cultural Center New York listed a Hyuna Park Trio concert at Birdland on June 20, 2019, featuring the album's music, and George W. Harris reviewed it for Jazz Weekly that September. All About Jazz ran an Italian-language review by Angelo Leonardi in April 2020. In August 2019 Jazz Generation's Keyed Up! program profiled her as she arrived in Banff for a jazz workshop.

Her recorded work since then has mostly been as a sideman. Discogs credits her on piano on the vocalist Alexia Gardner's Feeling The Love, Songs of My Mother, Songs of My Father (2023, recorded March 2023 in Paramus, New Jersey) and on trombonist John Yao's big band album Points In Time (2025), recorded in February 2024 in Mount Vernon, New York, on which the alto saxophonist Billy Drewes also plays. Discogs also lists her on piano on the 2014 EP Moongirl by the singer Tatiana Eva-Marie. The violinist Seoyeon Im credits her as pianist on New World (2026), alongside Sloniker. Her own website says she has appeared on more than two dozen albums, and Discogs lists only four releases, so the discography here is a floor, not a count.

Her website also says she leads the Hyuna Park Trio and co-leads ensembles with the trombonist Luis Bonilla and the bassist Martin Pizzarelli, and that she works regularly with Jerry Bergonzi, Vincent Herring, Danny Jonokuchi and John Yao. Her listed performance history includes Birdland, Zinc Bar, Iridium, Smalls, The Django, the Kennedy Center, the United Nations and an evening at the Decatur House Museum in Washington on March 6, 2023. A promoter biography adds tours of Japan, Korea, China, France, Switzerland and the Canary Islands, with no dates or venues. On December 21, 2025 she played piano with the Korean-born vocalist Hyeonseon Baek and her quartet The Bridge at Dada in Queens, a concert Korean Cultural Center New York listed.

In September 2026 she led her trio at Dizzy's Club in New York from September 3 to 5, with Sloniker on bass, David Hawkins on drums and the Swiss trombonist Amadis Dunkel as a guest. She is scheduled to play Jazz Vespers at St. Peter's Church on November 15, 2026.

Park describes her music as rooted in the jazz tradition while taking in classical and Korean folk influences. Her website calls her playing energetic and hard-swinging and names straight-ahead jazz, classical influences and Korean folk traditions as the three strands of her writing. A Dizzy's Club listing says her music is inspired by Kenny Kirkland and Mulgrew Miller, and she told Jazz Generation in 2019 that she had been listening to Herbie Hancock, Mulgrew Miller, the SFJAZZ Collective and Joe Henderson's big band album. The same interview names the gayageum player Sung Geumyeon's recording of the sanjo form, which she admires for its swing and groove with the janggu drum.

The Korean element in her own account is rhythmic. She says Korean grooves and rhythms offer many variations and that the space between the beats reminds her that silence can be a beautiful tool in music. Korean Cultural Center New York's description of Her Morning Waltz adds her personal connection with nineteenth-century classical piano music and Korean folk music concepts, and the album includes an original titled "The Stars Fell On Seoul."

Jazz Weekly's review hears a warm touch and a lyrical sense, bebop playing in the manner of Bud Powell on "Driving In New York," and a confident reading of Gershwin's "They Can't Take That Away From Me" and of Antonio Carlos Jobim's "The Boy From Ipanema." The review also singles out the closing solo piece "Outro" and says she is as strong alone as she is as part of a team. Everything else on the album except the two standards is her own writing and arranging.

No long interview in which she lists her influences in more detail was found, so this section stays with her own statements, her website and the reviews.
