Fujiwara no Ryoshi (藤原 旅子, also read Fujiwara no Tabiko; 759–788) was a Japanese noblewoman of the Nara period. She was a consort to Emperor Kanmu and the mother of Emperor Junna.

Fujiwara no Ryoshi was born in 759^[1] to Fujiwara no Momokawa^[1] and Fujiwara no Moroe (藤原諸姉),^[1] a daughter of Fujiwara no Yoshitsugu.^[1] Like many Japanese noblewomen of the pre-modern era, the correct reading of her given name is uncertain,^{[citation needed]} and the readings Ryoshi^[1] and Tabiko^[1] are speculative on and kun readings, respectively.^{[citation needed]}

In Enryaku 4 (785) she was given the Junior Third Rank.^[1] In the first month of the following year, she bore Emperor Kanmu the prince, Prince Ōtomo (大伴親王 Ōtomo-shinnō, later to ascend to the throne as Emperor Junna)^[1] and became Emperor Kanmu's consort (夫人 bunin).^[1]

She died in 788,^[1] at the age of 30 (by Japanese reckoning),^[1] and was posthumously granted the Senior First Rank^[1] and the title of empress (妃 kisaki).^[1] Subsequently, in Kōnin 14 (823) with the accession of her son, she was granted the title of Grand Empress (皇太后 kōtaigō).^[1]
