The Textus Roffensis, fully titled the Textus de Ecclesia Roffensi per Ernulphum episcopum and sometimes also known as the Annals of Rochester, is a mediaeval manuscript that consists of two separate works written between 1122 and 1124. It is catalogued as "Rochester Cathedral Library, MS A.3.5" and as of 2023 is currently on display in a new exhibition at Rochester Cathedral in Rochester, Kent. It is thought that the main text of both manuscripts was written by a single scribe, although the English glosses to the two Latin entries were made by a second hand. The annotations might indicate that the manuscript was consulted in some post-Conquest trials. However, the glosses are very sparse and just clarify a few uncertain terms. For example, the entry on f. 67r merely explains that the triplex iudiciu(m) is called in English, ofraceth ordel.

Ernulf was a French Benedictine monk who became prior of Christ Church in Canterbury, abbot of Peterborough, and bishop of Rochester in England. A jurist and an architect as well, he was responsible for greatly expanding Canterbury Cathedral during his time there.
