Fujiwara no Yoritada (藤原 頼忠; 924 – 31 July 989), the second son of Saneyori, was a kugyo (high-ranked Japanese noble) who served as regent for Emperor En'yū and Emperor Kazan.
His elder brother from the same mother Fujiwara no Atsutoshi died before their father's death.
In 977 he became Sadaijin, and when his cousin, the regent Fujiwara no Kanemichi was in a critical medical condition, he ceded the position of Kampaku (regent) to Yoritada, instead of his rival brother Kaneie.
His poet son Fujiwara no Kintō compiled the Shūi Wakashū, and also a collection of Chinese verse and prose (~600 selections) and 25 Japanese poems in his Wakan Rōeishū (和漢朗詠集), a widely admired collection that helped spread the influence of Chinese culture (and especially the poetry of Bai Juyi) in the Japanese Imperial court.
Kintō's collection would be imitated by a successor, Fujiwara no Mototoshi's Shinsen Rōeishū (新撰朗詠集).
