Yūryaku Seamount (雄略海山) is an underwater volcano (seamount) of the Hawaiian–Emperor seamount chain in the Pacific Ocean. Yūryaku is an extinct volcano.
The seamount is also known as the "Yūryaku Guyot" because it has a flat top. This undersea geologic feature is also called a "guyot" or "tablemount".
This seabed mountain is named after Emperor Yūryaku of Japan.
The last eruption from Yūryaku seamount was 43 million years ago.
