The Seven-Branched Sword (七支刀) is a ceremonial sword believed to be a gift from the king of Baekje to a Yamato ruler.

It is an iron sword with six branch-like protrusions along the central blade. The original sword has been conserved since antiquity in the Isonokami Shrine in Nara Prefecture, Japan and is not on public display. An inscription on the side of the blade is an important source for understanding the relationships between kingdoms of the Korean peninsula and Japan in that period.
