Fujioka Keijiro (藤岡屋慶次郎; fl. c. 1834 - 1881), often publishing as Shōeidō (松栄堂), Shōrindō (松林堂), of Fujikei (藤慶), was a publisher of the late Edo and early Meiji periods. Originally specializing in nishiki-e woodblock prints, including those by leading artists of the day, such as Hiroshige, Sadahide, and Utagawa Yoshitora, the firm later moved into book publishing, including textbooks for the Meiji-era Ministry of Education. Fujioka Keijiro's grandson took over management of the firm in the 1890s. In 1903, he founded Nippon Shoseki Co., Ltd. (日本書籍株式会社), a prominent book publisher of the late Meiji through early Showa eras.
