Shinsen Shōjiroku (新撰姓氏録, "Newly Selected Record of Hereditary Titles and Family Names")[a] is an imperially commissioned Japanese genealogical record.
Thirty volumes in length, it was compiled under the order of Emperor Saga by his brother, the Imperial Prince Manda (万多親王, 788–830).
The book itself has been lost, but its table of contents and fragments remain.
According to the preface, the record contains genealogical records for 1182 families living in the Heian-kyō capital and the Kinai region (encompassing Izumi, Kawachi, Settsu, Yamashiro, Yamato), which means "close to capital"; but the preface warns even this record comprises less than half of all the surnames in circulation there.
It categorizes these by their family roots: A total of 117 are listed as uncategorized.
