Hirata Moritane (平田 盛胤, 1863-1945) was a Japanese Shinto priest and scholar of kokugaku.

He was one of the heirs of the legacy of Hirata Atsutane, and during his lifetime was considered a leading figure in Tokyo's system of Shinto shrines.

During the 1890s, Moritane also cooperated with fellow kokugakusha Hayashi Mikaomi (林 甕臣, 1845-1922) at the latter's private academy in Tokyo where the two taught courses in traditional Japanese writing and stenography.

One of his students was Miyaji Itsuo [ja], a senior priest of Ise Grand Shrine and official of the Ministry of the Imperial Household.

In 1942, the ageing Moritane presided over the state funeral for Japanese military personnel who died at Pearl Harbor.
