Jung Ho-seok (Korean: 정호석; born February 18, 1994), known professionally as J-Hope (제이홉; stylized in lower case), is a South Korean rapper, singer, songwriter, dancer, and record producer. He made his debut as a member of South Korean boy band BTS in 2013, under Big Hit Entertainment. J-Hope released his first solo mixtape, Hope World, in 2018. It was received positively by critics and peaked at number 38 on the US Billboard 200, the highest-charting album by a Korean solo artist at the time. He became the first member of BTS to enter the Billboard Hot 100 as a soloist in 2019, when his single "Chicken Noodle Soup", featuring singer Becky G, debuted at number 81. In 2022, J-Hope released his debut studio album Jack in the Box. In 2023, he released his single "On the Street" with J. Cole.
J-Hope was born Jung Ho-seok on February 18, 1994, in Gwangju, South Korea, where he lived with his parents and older sister, Jung Ji-woo. His family is from the Hadong Jeong clan.
In March 2019, J-Hope enrolled at Hanyang Cyber University for the Master of Business Administration program in Advertising and Media. He previously graduated from Global Cyber University with a degree in Broadcasting and Entertainment.
Before debuting with BTS, J-Hope was part of an underground dance team called Neuron, and took dance classes at Gwangju Music Academy for six years, from fourth grade to his first year in high school when he signed with Big Hit Entertainment. He was relatively well known for his dance skills, and won various local prizes, including first place in a national dance competition in 2008. His dancing eventually led to an interest in singing, and he auditioned to become an idol trainee. While a trainee, J-Hope appeared as a featured rapper on singer Jo Kwon's song "Animal", released in 2012.
On June 13, 2013, J-Hope made his debut as a member of BTS on M! Countdown. He was the third member to join the band as a trainee after RM and Suga. Under the band's name, he has performed four solo songs: "Intro: Boy Meets Evil", "Mama", "Trivia 起: Just Dance", and "Outro: Ego". The first two were released in 2016 as part of BTS' second studio album Wings. Lyrically, "Boy Meets Evil" was about "the thoughts of a boy faced with the evil that is temptation" and showcased J-Hope's rapping abilities, while "Mama" was a "quirky hip-hop" ode of appreciation to his mother that "captures his animated delivery and onstage style. "Just Dance", released in 2018 on the band's fourth studio album Love Yourself: Answer, was a "funky hip-hop" song that "uses the titular activity as a metaphor for love". "Outro: Ego", also an upbeat, "funky" track, from 2020's Map of the Soul: 7, reflected on J-Hope's career and the decisions and hardships he faced through the years, additionally addressing the "dichotomy between his stage persona and his birth identity".
J-Hope also collaborated with bandmate V and Swedish singer Zara Larsson on the single "A Brand New Day" for the official soundtrack of the BTS World mobile video game. The single was released on June 14, 2019.
J-Hope's first solo release, outside of his work with BTS, was the 2015 rap track "1 Verse"—it sampled "El Chapo" by The Game—uploaded for free via the band's SoundCloud. A darker sound in comparison to what he would become known for later on in his career, the song addressed J-Hope's haters, particularly those who continuously listened to his music just to criticize him, and showcased his ability to mold his vocals and rapping style to reflect the content of his lyrics.
On March 1, 2018, J-Hope released his first solo mixtape Hope World worldwide, accompanied by a music video for the lead single "Daydream". A music video for the B-side single "Airplane" followed on March 6. The mixtape debuted at number 63 and peaked at number 38 on the Billboard 200, making him the highest-charting Korean solo act on the ranking at the time. Six of the album's tracks entered the World Digital Song Sales chart, with "Daydream" topping the chart and making J-Hope one of only ten Korean artists, including BTS, to reach number one. The success of his solo debut led to him ranking at number three on the Emerging Artists chart and peaking at number 91 on the Artist 100; he became the fifth Korean artist and second Korean soloist (after Psy) to chart on the latter. Hope World charted in ten countries worldwide, and "Daydream" charted in three. The mixtape ranked at number five on Billboard's year-end World Albums Chart for 2018. J-Hope released the full version of the mixtape's closing track, "Blue Side (Outro)", for free via BTS' SoundCloud page on March 1, 2021, in celebration of Hope World's third anniversary.
In 2019, J-Hope released a free collaboration single, "Chicken Noodle Soup", featuring American singer Becky G, on September 27. The track debuted at number 81 on the Billboard Hot 100, making J-Hope the first member of BTS to chart on the Hot 100 as a solo artist, the third Korean solo artist to rank on the chart (after Psy and CL), and the sixth Korean artist overall to do so. "Chicken Noodle Soup" also became J-Hope's second song to debut at number one on the World Digital Song Sales chart.
On June 14, 2022, Hybe Corporation announced that J-Hope would be the first member of BTS to begin promotions as a solo artist. His debut solo album Jack in the Box, released on July 15, was preceded by the lead single "More" on July 1. J-Hope made his performance debut at Lollapalooza on July 31, as the headlining act for the final day of the festival. He became the first South Korean artist to headline a main stage at a major United States music festival. In September, J-Hope featured on the single "Rush Hour" by Crush. He was nominated for six awards, including Artist of the Year and Song of the Year, at the MAMA Awards, and made his solo performance debut at the show as the headliner for day two of the event, on November 30. He also made his solo performance debut at Dick Clark's New Year's Rockin' Eve on December 31.
A documentary titled J-Hope in the Box, chronicling the making of J-Hope's debut album and his appearance at Lollapalooza, was released for streaming globally on Weverse and Disney+ in February 2023. He was announced as a brand ambassador for Louis Vuitton that same month. J-Hope released the collaboration single "On the Street", with American rapper J. Cole, on March 3. He became the first member of BTS to earn a top-40 entry on the UK Singles Chart following its debut at number 37, setting a new record as the highest-charting Korean soloist in the history of the chart at the time. He also earned his highest peak on the US Hot 100 at number 60. Big Hit released a six-part docuseries titled Hope on the Street in March 2024, accompanied by the special album Hope on the Street Vol. 1. Recorded before J-Hope began his mandatory military service a year prior, both projects explored his artistic roots and street dance background. The first episode aired globally on March 27 on Prime Video and on TVING in South Korea, while the album followed on March 29, with "Neuron" featuring Gaeko and Yoon Mi-rae as its lead single.
J-Hope participated in Le Gala des Pièces Jaunes, a charity event hosted by the First Lady of France, Brigitte Macron, in January 2025. Held at La Défense Arena in Paris, he performed a three-song set as the show's opening act—per Macron's request—before a crowd of 35,000 attendees, marking his first musical appearance following the completion of his military service three months prior. His first solo tour, Hope on the Stage, was announced that same month. It began at the end of February in Seoul, then expanded to major cities in Asia and North America; it concluded with a two-day concert on June 13 and 14 at the Goyang Sports Complex Main Stadium in Goyang. In February 2025, J-Hope was announced as one of the headliners at 2025 Lollapalooza Berlin, which took place on July 12 and 13 at Olympic Park and the Olympic Stadium in Berlin.
His stage name, J-Hope (제이홉), comes from his desire to represent hope for fans, as well as to be "the hope of BTS". It is also a reference to the myth of Pandora's box, as after the box was opened and all the evils inside were released to the world, the only thing left was hope.
