Hong Jin-kyung

Hong Jin-kyung (, born December 23, 1977) is a South Korean entrepreneur, model, host, comedian and actress. She is a host of the Netflix dating show Single's Inferno and has been a cast member on several Korean variety shows such as Sister's Slam Dunk and Beat Coin.

Career

Hong Jin-kyung was born as the eldest of two children (one son and one daughter). In 1993, during her first year of high school, she made her debut in the entertainment industry by receiving the Best Pose Award at the 2nd SBS Supermodel Contest.

Although she began her career as a model, Hong gained significant recognition after appearing as a guest on a variety show, where she stood out as a witty and charismatic host. This led her to become more active as a show MC rather than continuing solely as a model. Her comedic talents propelled her to stardom, and as her popularity grew, she also found great success in the modeling industry.

In 2004, Hong founded a food company called "Hong Jin-kyung Co., Ltd." and launched a kimchi business. Over time, the product line expanded to include dumplings, japchae, galbi, gomguk, doenjang, gochujang, and various sauces. Her products have been sold on major Korean home shopping channels such as CJ, GS, Hyundai, and Home&Shopping. The company maintained the No. 1 spot in online kimchi sales for an extended period.

In 2021, Hong Jin-kyung launched a YouTube channel titled "Study King Jin Genius" (공부왕 찐천재). As of 2025, the channel has surpassed 1.7 million subscribers. It has become widely popular both domestically and internationally.

The channel features a diverse lineup of high-profile guests, including presidential candidates, K-pop superstars such as Blackpink, Aespa, as well as legendary Hallyu figures like Lee Young-ae of Dae Jang Geum (Jewel in the Palace) fame.

Since the 2010s, Hong has been recognized as a versatile entertainer, active across all areas of the entertainment industry. Her work spans modeling, comedy, TV hosting, radio DJing, acting, and even singing, as seen in her participation in the project girl groupUnnies.

Hong is also known for her philanthropic efforts. Since 2005, she has been supporting Yeomyung School, a shelter and educational facility for North Korean defectors. She has donated funds and supplies to a total of 12 organizations, including childcare centers, youth study rooms and shelters, UNICEF, and World Vision. Her efforts include vocational training sponsorships for orphans in South Korea and monthly donations to support 30 children and their communities across Asia.

In early 2012, she established a daycare center named "Rael Daycare" in Doba, Chad, Africa, named after her daughter Rael. In 2025, she launched a campaign with World Vision to help protect young girls in Africa from early and forced marriages.
