Katsura Hirozumi

was a Japanese samurai and commander of the Sengoku period.

Hirozumi's relative Saka Hirohide rebelled against Mōri Motonari, as Hirohide was dissatisfied with Motonari's succession to the family headship. His son Katsura Motozumi became one of the most important retainers of the Mōri clan. Motozumi served Motonari and Mōri Terumoto until his death.

In popular culture Hirozumi was portrayed by actor Masao Kusakari in the 1997 Japanese television series Mōri Motonari
