Amago Yoshihisa (尼子 義久; 1540 - 1610) was a Japanese warlord. He lost to Mori Motonari.

He was the first son of Haruhisa. He continued the family fight against the Mori clan. While besieged in Toda Castle, Yoshihisa had a retainer, Moriyama Hisakane executed. This caused most of his remaining men to desert. With no hope of holding the castle, Yoshihisa fled and became a monk.
