South Korea is one of the largest and most sophisticated PR markets in the Asia-Pacific region. Samsung, Hyundai Motor Group, LG, SK Group, and Naver all run major in-house communications operations, but the agency landscape supports a complex mix of K-beauty, K-pop, gaming, fintech, healthcare, and emerging technology clients alongside the conglomerate-driven economy. Seoul concentrates virtually all of the country's major PR firms, and the market splits broadly between domestic specialists with deep media relationships and the local offices of global networks. The agencies below represent the leaders.
Edelman Korea. Operating in Seoul since 1993, Edelman Korea is the largest international PR agency in the country and consistently ranked among the most influential Korean communications firms. The agency was the first in Korea to introduce brand journalism as a working discipline, and its current practice spans digital, performance, influencer marketing, risk management, and traditional PR. Edelman's Seoul office is widely regarded as the most multicultural PR team in the city.
KPR. One of the longest-operating Korean independents, KPR has been working with both domestic conglomerates and multinational clients for more than three decades. Its core capabilities are consumer marketing communications, trend research, sports marketing, and social media.
Prain Global. Founded in 2000, Prain has grown into one of South Korea's largest integrated PR firms, with a partnership relationship with Ketchum that extends its global reach.
Medicom. Seoul-based and founded in 1997, Medicom is one of the largest independent agencies in Korea, with a particular specialty in video news releases and digital and social work.
KorCom Porter Novelli. Established in 1995, KorCom is the Korean partner of Porter Novelli within the Omnicom Group network, with access to more than 100 global offices across 60 countries.
CK (Communications Korea). Established in 1987, CK was the first PR agency founded in South Korea. Over its history the firm has represented more than 300 clients across consumer, technology, and public affairs work. CK is widely regarded as the country's leading public affairs firm.
Insight Communications Consultants. Founded in 2004 by Michael Breen, Insight is the exclusive Korean partner for FTI Consulting. The firm is staffed by former senior journalists from leading international news outlets and experienced Korean PR specialists.
M&K PR Consulting. Established in 2002, M&K has built a steady practice as a dedicated and reliable PR partner for both Korean and multinational clients.
Access Communications. Established in 1995, Access Communications & Consulting is a strategic PR and business communications firm that has helped raise Korea's PR service standards over its three decades of operation.
Chayun Public Relations (CPR). Established in 1992, CPR is one of the longest-operating integrated communications groups in Korea, offering PR and media management, brand marketing, corporate communications, digital marketing, social media, and market access.
Edge Communications. A Seoul-based agency focused on raising key stakeholder awareness for international clients, Edge specializes in helping foreign brands navigate Korean media.
Strategic Public Relations Group (SPRG / INR). SPRG is one of the largest PR groups in the Asia-Pacific region. Its Korean affiliate INR provides expertise in media relations, healthcare, public affairs, financial PR, real estate, technology, consumer products, and international marketing.
Hill+Knowlton (now Burson Korea), FleishmanHillard Korea, and Weber Shandwick Korea. The major holding-company networks all operate in Seoul. Burson leads on corporate, public affairs, and government work; FleishmanHillard runs corporate, technology, and crisis programs; Weber Shandwick anchors complex multi-market campaigns.
For brands in the Korean market, agency selection generally splits between three needs: localized cultural and media expertise (KPR, Medicom, CK, Prain, CPR); global coordination on multi-market campaigns (Edelman, Burson, FleishmanHillard, Weber Shandwick, KorCom Porter Novelli); and specialist work in public affairs, financial PR, or specific verticals (CK, Insight, SPRG/INR).
