Princess Yoshiko, or Yoshiko Naishinnô, was empress consort to Emperor Kôkaku.
She was the only daughter of Emperor Go-Momozono; after Go-Momozono died without male heirs, Yoshiko was married to a member of a collateral branch of the imperial family, who then took the throne as Emperor Kôkaku.
She gave birth to her third child, Prince Masuhito, in 1800, but the child died only three months later.
