The flag of Hiroshima Prefecture (Japanese: 広島県旗, Hepburn: Hiroshima-ken ki) is a crimson field charged in the center with a white, stylized representation of the initial mora hi () in katakana.[1] On its own, the charge is the emblem of Hiroshima Prefecture (広島県章, Hiroshima-ken shō) and shares the same crimson color as the field of the flag. The overlapping circles of the emblem represent "the growing progress and development" of Hiroshima Prefecture.[1]

The emblem was adopted on 23 July 1966, while the flag was established by Hiroshima Prefectural Notification No. 572, enacted on 16 July 1968.[1][2] The flag's width-to-length ratio is 3:5 and its shade of red is crimson, Munsell values 4R 4/11 (Japan Industrial Standards).[2]
