Sonpi Bunmyaku (尊卑分脈) is a Japanese genealogical text. Originally written by Tōin Kinsada in the late 14th century, it was either 15 or 16 volumes in length. This was followed by re-edited editions eventually bringing the text to thirty volumes in length. The full title is 新編纂圖本朝尊卑分脈系譜雜類要集, and it is an old Japanese book that is a collection of genealogies of noble people. The book is considered one of primary sources for the study of genealogies of nobility in Japan, in particular for nobles of Heian and Kamakura periods. The book is also known under the title Shoke Ōkeizu (諸家大系図) and Shoke Keifuden (諸家系譜伝). Not every part of the book survived, but those that survived tend to be detailed about members of Fujiwara clan and Minamoto clan. Like other major genealogies books, the real names of women (e.g., Murasaki Shikibu), except for very few, were not mentioned in the book.
