Tishyaraksha or Tissarakkhā (c. 3rd century BCE) was the last wife of the third Mauryan emperor, Ashoka. According to the Ashokavadana, she was responsible for blinding Ashoka's son and heir presumptive Kunala. She married Ashoka four years before his death. She was very jealous of the attention paid by Ashoka to the Bodhi-tree, and caused it to be killed by means of poisonous thorns.
