Sūn Zhào 孫兆 (fl. 1057–1067, 宋), Northern Sòng official-physician and a member of the imperial Bureau for Editing Medical Books (Jiàozhèng yīshū jú 校正醫書局) under 林億. He served as Jiàngshì láng shǒu Diànzhōng chéng 將仕郎守殿中丞 with the bureau title 重校誤 (“Senior Collator of Errata”). His most prominent independent contribution was the editorial leadership of the校正醫書局’s edition of the Wàitái mìyào (KR3e0015), presented to the throne in Zhìpíng 4 (1067); the surviving Sòng print of the Wàitái under the printing-block colophon names him as the principal collator. He participated in the bureau’s collation of the Sùwèn (KR3e0001) and other foundational classics. He has no transmitted free-standing biographical record.
