Shinkokushi

is an unfinished Japanese official historical work compiled, in part, by the early Heian period scholar , grandson of Ōe no Otondo, who had been one of the compilers of the Nihon Montoku Tennō Jitsuroku. After Asatsuna's death in 957, his cousin Ōe no Koretoki became the head compiler. It was supposed to succeed the Six National Histories.

The Shinkokushi is recorded in the ' as having forty volumes and covering the reigns of Emperor Uda (887-897) to Emperor Daigo (897-930). However a later work, the ', states that the Shinkokushi was fifty volumes and included the reign of Emperor Suzaku (930-946) as well as Uda and Daigo. Because of the differences in size, lack of a formal title, and that no record of a presentation of the work survives, it is believed that the Shinkokushi was an unfinished manuscript. As a manuscript, the entirety of the Shinkokushi does not survive but instead portions of it have been passed down in other works. ==Notes==
