Takasue's Daughter, or Sugawara no Takasue no musume (菅原孝標女?, c.1008 - after 1059), was a Japanese author. "Sugawara no Takasue no musume" means a daughter of Sugawara no Takasue. Her real name is unknown. However, British scholar Ivan Morris, who translated her diary, referred to her as Lady Sarashina.
She is known for her classic Heian period travel diary, the Sarashina Nikki. In his later years, Fujiwara no Teika admired it enough to copy it out for his own perusal.
