Buyeo or Puyŏ, Fuyu in Chinese, is an ancient Korean kingdom located from today's Manchuria to northern North Korea, from around the 2nd century BCE to 494.

Its remnants are absorbed by the neighboring and brother- kingdom of Goguryeo in 494.

Both Goguryeo and Baekje, two of the Three Kingdoms of Korea, consider themselves its successor nation.Although records are sparse and contradictory, it is speculated that in 86 BCE, Dongbuyeo (Eastern Buyeo) branched out, after which the original Buyeo is sometimes referred to as Bukbuyeo (Northern Buyeo).

Jolbon Buyeo was a small tribal state situated in north of the Korean peninsula and Manchuria.

According to Samguk Sagi, in 504, the tribute emissary Yesilbu mentions that the gold of Buyeo can no longer be obtainable for tribute as Buyeo has been driven out by the Malgal and the Somna and absorbed into Baekje.

It is also shown that the Emperor Shizong wished that Buyeo would regain its former glory.

In 538, long after the fall of Buyeo, Baekje renames itself Nambuyeo (Southern Buyeo).
