Early in 2025 Yongin mayor Lee Sang-il announced his intention to launch a professional football team in the city. The commitment was ratified in May 2025 and Kim Jin-hyung was appointed as chairman. The club subsequently appointed
Choi Yun-kyum as Yongin FC's first manager and
Lee Dong-gook as technical director. In August 2025, the club received approval to join the
K League, confirming its intention to participate in the
2026 K League 2. Ahead of the 2026 season, technical director Lee stated that the club aimed to "survive in midtable" in its first two years before making a push for a chance at promotion to
