Seok Nae-hae (?-230) was the tenth king of Silla (Naehae Isageum, r. 196-230). His grandfather was Beolhyu Isageum, his father Seok I-mae and his mother Lady Naerye. His queen is said to have been a sister of Jobun Isageum.
After Beolhyu's crown prince Seok Gol-jeong and second son I-mae died first, Nae-hae took the throne in place of Gol-jeong's young son Jobun. His son was the crown prince Seok U-ro, and his daughter Lady Aihye became queen of Jobun Isageum.
When the Eight Port States attacked Gaya in 209, Crown Prince Uro and Ieum led troops of the six Jinhan districts to the rescue and freed over 6,000 captives. Between 214 and 224 Silla faced Baekje at Yogeoseong, Jangsanseong and Uduju, while keeping peace with Gaya and answering Wae and Malgal raids.
After Beolhyu's eldest son Gol-jeong and second son I-mae died, Gol-jeong's son Jobun was still young, so I-mae's son Nae-hae is said to have succeeded. He married Jobun's sister and gave his daughter Lady Aihye to Jobun, binding the two branches together.
When the Eight Port States attacked Gaya in 209, Crown Prince Uro and Ieum led troops at Gaya's request and won. In 218, when Baekje besieged Jangsanseong, Nae-hae is said to have taken the field himself and driven them off. Close exchange with Gaya is a hallmark of his reign.
The location of his tomb is unknown.
His children were the crown prince Seok U-ro and Lady Aihye, queen of Jobun Isageum. U-ro's son Heulhae later became the sixteenth king.
