Maruya Tetsujirō (丸屋鉄次郎; fl. c. 1860 - 1890), also known as Tetsujirō Kobayashi (小林鉄次郎), was a Japanese publisher based in Edo / Tokyo. He published a wide range of nishiki-e prints, including those by the Utagawa school of woodblock artists, such as Hiroshige II's (二代目歌川広重) fascinating 1863 triptych of London (英吉利西龍道大港). His professional name strongly suggests and affiliation with the publishing lineage of Maruya Jianpachi (丸屋甚八).
