Henry de Cornhill was a medieval English priest.
Cornhill was appointed chancellor of the Diocese of London in 1217 by the papal legate Guala Bicchieri.
He also held the prebends of Finsbury and Weldland in the same diocese.
He remained in that office until at least 28 October 1253, his last appearance in a document.
He likely continued to hold the office until his death, which occurred before 26 August 1254.
