Kim Su-ro, The Iron King (Korean: 김수로; RR: Kim Su-ro) is a 2010 South Korean television series on the life of Suro of Geumgwan Gaya, starring Ji Sung, Bae Jong-ok, Yu Oh-seong, Seo Ji-hye, Go Joo-won, Kang Byul and Lee Pil-mo.

[1] It aired on MBC from May 29 to September 18, 2010, on Saturdays and Sundays at 21:45 for 32 episodes.

The ₩20 billion-budget historical drama charts the life of Kim Su-ro, who unified 12 small countries to become the legendary founder and ruler of Geumgwan Gaya, the city-state of the Gaya confederacy which dominated sea trade and iron working during the Three Kingdoms period in the 5th century.

Kim Su-ro's fiery temperament, charisma and intelligence are his only defense in an extended political struggle, with competition for the throne from his half-brother and lifelong rival, Ijinashi (first king of the state of Daegaya), his former friend Seok Tal-hae, and the dangerous ambitions of Shingwi Ghan.

After she was fired in June 2010, writer Kim Mi-sook sued the production company for damages amounting to ₩576 million (or US$478,600).
